In this sports based classification question, select the odd word from the given cricket related options.

Introduction / Context:
This question is a simple classification problem drawn from the domain of cricket. All four words refer to familiar roles or positions associated with a cricket match. You must identify which word does not belong to the same group as the others. Such general knowledge based reasoning questions check whether you can quickly categorize roles and distinguish participants from officials.

Given Data / Assumptions:
- The options are Batsman, Umpire, Bowler, and Wicket-keeper.- All four terms are connected to the game of cricket.- The likely basis of classification is whether the term represents a player or an official.

Concept / Approach:
In a typical cricket match, there are players on the field and there are match officials. Batsman, bowler, and wicket keeper are playing roles in a team, while the umpire is responsible for decision making and rule enforcement. The odd one out is therefore the only non player role in the list.

Step-by-Step Solution:
Step 1: A batsman is a player who faces the ball and attempts to score runs.Step 2: A bowler is a player who delivers the ball to the batsman.Step 3: A wicket keeper is also a player, positioned behind the stumps to catch and stump.Step 4: An umpire is not a player but an official who supervises the match and makes decisions on dismissals, boundaries, and other rules.Step 5: Three options describe on field players, while one describes a match official.

Verification / Alternative check:
Imagine the team sheet. The batsman, bowler, and wicket keeper are included in the playing eleven. The umpire is listed separately as an official appointed by the cricket board. This mental picture confirms the classification.

Why Other Options Are Wrong:
Batsman: Clearly a player role.Bowler: Also a core player role.Wicket-keeper: Another playing position on the team.

Common Pitfalls:
Sometimes students think only in terms of fielding or batting roles and forget that officials are not part of the team. Remember that the odd one can come from outside the main group, not just from a different playing position.

Final Answer:
The odd word is Umpire because it refers to an official, while the other three are playing positions.
