In the One Day International match between India and Pakistan at Jaipur on 2 October 1983, which new limited overs cricket rule was introduced for the first time?

Introduction / Context:
Limited overs cricket has evolved through several rule changes aimed at making the game more competitive and spectator friendly. One such important innovation was the introduction of field restrictions, which later developed into the concept of powerplays. Historical One Day International matches often serve as markers for the first use of specific rules. The India Pakistan ODI played at Jaipur on 2 October 1983 is remembered for being the first match where a key field restriction rule was enforced. This question tests your knowledge of that landmark rule change.

Given Data / Assumptions:

• The match took place between India and Pakistan at Jaipur on 2 October 1983.
• It was a One Day International (ODI) match.
• The question asks which new rule was introduced on this occasion.
• The options mention overs limit, field restriction, overthrow runs, and accounting of no balls and wides.

Concept / Approach:
The key concept is the history of fielding restrictions in ODI cricket. Early ODIs had fewer regulations on the placement of fielders. As administrators wanted to encourage more attacking play, they introduced rules that required a minimum number of fielders to be kept inside a certain distance from the batsman during specified overs. This development began with simple field restriction rules before evolving into powerplays. The Jaipur ODI of 1983 between India and Pakistan is noted in cricket history for introducing such a field restriction rule for the first time, making option B the correct choice.

Step-by-Step Solution:
Step 1: Identify the match in question: India versus Pakistan at Jaipur on 2 October 1983. Step 2: Recall that the early 1980s were a period of experimentation with ODI rules to increase scoring and viewer interest. Step 3: Remember that this particular match is associated with the debut of field restrictions in ODIs, requiring certain fielders to stay inside a circle during initial overs. Step 4: Examine the options and note that option B mentions the introduction of a field restriction rule. Step 5: Select option B as the correct answer, matching the historical rule change to this match.

Verification / Alternative check:
You can verify by cross checking with what other options imply. The standard ODI limit of overs per side stabilised at 50 overs around that period, but that change is not specifically tied to this single match. Overthrow runs being added to the batsman score and no balls and wides being debited to the bowler analysis are long standing scoring conventions rather than one time innovations. On the other hand, field restriction regulations are widely recorded as having been experimented with in the early 1980s, and the India Pakistan Jaipur match is cited as the first ODI where this rule was applied. This comparison supports option B as the only historically meaningful new rule introduced in that match.

Why Other Options Are Wrong:
Limit of overs was reduced to 50 overs per side: While ODI formats did move towards a 50 over standard, this change is not uniquely tied to the Jaipur 1983 match and is not described as a one match rule introduction in history notes.
Overthrow runs were added to the batsman score: Overthrow scoring was already part of cricket scoring methods, so it was not a brand new rule originating from this specific match.
No balls and wides were debited to the bowler analysis: These scoring conventions are integral to scorecards and were not introduced suddenly in a single ODI at Jaipur; they evolved over time and are not highlighted as a new rule for that date.

Common Pitfalls:
Some candidates misinterpret the question and think about general scoring laws instead of rule changes specific to ODI format development. Others may assume that 50 over limits or the treatment of wides and no balls must have started in a single match, which oversimplifies the history of the laws. To avoid such pitfalls, remember that the key innovation linked to early 1980s ODI experiments is field restrictions, which later evolved into more detailed powerplay rules. Linking the Jaipur 1983 ODI with the first use of field restrictions helps you answer correctly.

Final Answer:
In the India Pakistan ODI at Jaipur on 2 October 1983, the new rule introduced for the first time was that the rule of field restriction was introduced, so option B is correct.
