Which of the following contributions of Aryabhata is/are true?
- Earth rotates around a stationary Sun.
- Cause of solar and lunar eclipse.
- Nearly correct value of the circumference of the Earth.
Choose the correct option from the following.
Correct answer: D
Explanation
Aryabhata held that the Earth rotates on its own axis while the Sun stays fixed, which explains the apparent daily motion of the sky. He gave the scientific cause of solar and lunar eclipses as shadows cast by the Moon and Earth, rejecting the Rahu-Ketu myth. His estimate of the Earth's circumference was remarkably close to the modern value, so all three statements are correct.
