Explanation: Jawaharlal Nehru Stadium, located in Chennai, Tamil Nadu, is a significant multi-purpose sports stadium known for its distinctive elliptical shape. This stadium is a prominent venue for various sports events, including school sports days, making it a hub for sports activities in the region.
The stadium was named after Jawaharlal Nehru, the first Prime Minister of India, and it has been a landmark in Chennai since its construction. Its elliptical design is a notable feature that sets it apart from other stadiums in the city. The shape not only adds to the aesthetic appeal of the stadium but also provides a unique layout that can accommodate different types of sports and events.
In the context of the question, the reference to "KC's sports day" suggests that the stadium is used for school sports events. KC likely refers to Kamala Niketan, a well-known school in Chennai, which often uses Jawaharlal Nehru Stadium for its annual sports day. This aligns with the stadium's role as a hub for sports activities, making it a suitable venue for school events.
The other options provided do not fit the description given in the question. Chidambaram Stadium, while a significant cricket venue in Chennai, is not elliptical in shape and is primarily used for cricket matches. Anna Gem is not a recognized stadium or sports venue in Chennai, and St Louis School is a school name, not a stadium.
In summary, Jawaharlal Nehru Stadium is the correct answer because it is an elliptical stadium that serves as a hub for sports events, including school sports days, which aligns with the description provided in the question. Understanding the specific features and roles of different stadiums in Chennai is crucial for correctly identifying the venue described.
