Explanation: The question is designed to test the geographical knowledge of cities within Tamil Nadu, specifically focusing on the city of Coimbatore. Coimbatore, also known as Kovai, is a major city located in the western part of Tamil Nadu. It is known for its industrial and commercial activities, and it is a significant urban center in the state. The city is well-connected to other parts of India, including Delhi, through various modes of transportation such as air, rail, and road.
The context of the question is Tamil Nadu General Knowledge (GK), which means that the answer must be a city within the state of Tamil Nadu. Coimbatore fits this criterion perfectly, as it is a prominent city in Tamil Nadu. The question does not provide any additional information about Mala's reasons for moving to Delhi, but it is common for people to move from smaller cities or states to larger metropolitan areas like Delhi for various reasons such as better job opportunities, education, or lifestyle.
Shillong, on the other hand, is the capital city of Meghalaya, a state located in the northeastern part of India. It is not within the geographical boundaries of Tamil Nadu, and therefore, it cannot be the correct answer in the context of Tamil Nadu GK. The question is specifically designed to test the knowledge of cities within Tamil Nadu, and Shillong does not fit this criterion.
In conclusion, the correct answer is Coimbatore, as it is a city within Tamil Nadu and fits the context of the question. The question tests the ability to identify cities within a specific state and understand the geographical boundaries of Indian states. This type of question is common in competitive examinations that focus on state-specific knowledge, such as the Tamil Nadu Public Service Commission (TNPSC) exams and other state-level competitive exams.
