Consider the following statements about the megacities of India: 1. I. Population of each megacity is more than 5 million. 2. II. All the megacities are important sea ports. 3. III. Megacities are either national or State capitals. Which of these statements are correct?

1. Evaluate the statements about megacities in India around 2000. I. "Population of each megacity is more than 5 million." While definitions vary (often 10 million), using a 5 million threshold, major Indian cities like Mumbai, Delhi, Kolkata, Chennai, Bangalore, Hyderabad qualified or were close around 2000. This statement is considered correct in this context. II. "All the megacities are important sea ports." This is incorrect. Delhi, Bangalore, and Hyderabad are major inland megacities. III. "Megacities are either national or State capitals." This was largely true for the prominent megacities at the time: Delhi (National Capital), Mumbai (Maharashtra), Kolkata (West Bengal), Chennai (Tamil Nadu), Bangalore (Karnataka), Hyderabad (Andhra Pradesh). This statement is considered correct. 2. Statements I and III are correct, while II is incorrect.
