Which cricket stadium is widely regarded as having the largest playing area and boundary size in the world?

Introduction / Context:
Cricket stadiums vary not only in seating capacity but also in the size of their playing area and boundary dimensions. Some questions in sports general knowledge focus on which ground is the largest by boundary rather than by number of seats. This question asks which stadium is widely regarded as having the largest boundary size and playing area among the options given.

Given Data / Assumptions:

- The focus is on playing area and boundary size, not on seating capacity.- Options include stadiums in India and Australia: Rajiv Gandhi International Stadium, Melbourne Cricket Ground, Eden Gardens, and Greenfield International Stadium.- We assume common sports general knowledge that ranks stadiums by boundary length.

Concept / Approach:
Several articles and cricket analyses mention that the Melbourne Cricket Ground (MCG) in Australia has one of the largest playing areas and is often cited as the stadium with the largest boundary size among major international grounds. While some newer or renovated stadiums may have high seating capacity, the MCG retains a very large field with long square and straight boundaries. Therefore, we identify the MCG as the correct answer for size by boundary.

Step-by-Step Solution:
1. Remember that the question is not about which stadium holds the most spectators, but about boundary and ground dimensions.2. Recognize that Eden Gardens and Rajiv Gandhi International Stadium are large and historic, yet they are not commonly described as having the largest boundaries in the world.3. Greenfield International Stadium is a modern ground with good facilities, but its playing area is more typical of international standards, not exceptionally large by boundary.4. The Melbourne Cricket Ground is often described in commentary and articles as a huge ground with long boundaries that challenge batters.5. Based on this repeated description and standard sports references, select the Melbourne Cricket Ground, Australia.

Verification / Alternative check:
Cricket fans often hear commentators mention that hitting sixes at the MCG is harder because of the larger boundary distances compared to many other grounds. Diagrams of the MCG show long square boundaries and a large oval playing area. List style articles ranking stadiums by boundary size usually put the MCG at or near the top. In contrast, lists about seating capacity now mention stadiums like the Narendra Modi Stadium, but this question targets boundary size, supporting the choice of the MCG.

Why Other Options Are Wrong:
- Rajiv Gandhi International Cricket Stadium, Hyderabad: A major Indian venue but not widely cited as having the largest playing area globally.- Eden Gardens, Kolkata: Historically one of the largest stadiums by crowd capacity, yet its playing dimensions are not described as the largest in the world.- Greenfield International Stadium, Thiruvananthapuram: A modern, well designed ground but with boundaries that are within standard international limits rather than unusually large.

Common Pitfalls:
Many learners confuse “largest stadium” by capacity with “largest ground” by boundary, especially because different sources focus on different metrics. Hearing that an Indian stadium has the highest seating capacity may cause some to pick an Indian option by habit. To avoid this, always read whether the question is about seating, area, or boundary size. Here the words playing area and boundary size clearly point toward the MCG as the right answer.

Final Answer:
The correct option is Melbourne Cricket Ground, Australia, which is widely regarded as having one of the largest playing areas and boundary sizes among major cricket stadiums in the world.
