The Hindu, a leading English daily, is based in:

Chennai
Madurai
Coimbatore
Tiruchirappalli

The correct answer is Chennai.

The Hindu is an Indian English-language daily newspaper published by Kasturi & Sons Limited. It is one of the oldest and most widely circulated newspapers in India. The newspaper was founded in 1878 by G. Subramania Iyer, a Tamil scholar and social reformer. The Hindu is headquartered in Chennai, Tamil Nadu, India.

The Hindu has a strong focus on news and current affairs. It also has a wide range of features, including articles on politics, business, sports, culture, and entertainment. The newspaper has a reputation for its in-depth reporting and its commitment to independent journalism.

The Hindu is a popular choice for readers who want to stay informed about the latest news and developments in India and around the world. It is also a valuable resource for students and researchers who are looking for information on Indian history, culture, and society.

The other options are incorrect because they are not the headquarters of The Hindu. Chennai is the capital of Tamil Nadu and the sixth-largest city in India. It is a major center for business, education, and culture.
