With reference to the scientific and mathematical contributions of Aryabhata, consider the following statements: 1. Aryabhata formulated the rule for finding the area of a plane triangle as half the product of the base and the height. 2. In Aryabhatiya, he explicitly stated that the Earth is spherical and rotates on its own axis, causing day and night. 3. He calculated the value of Pi (π) to be 3.1416, which he described as an approximate (asanna) value. Which of the statements given above is/are correct?

Options:

• A: 1, 2 and 3
• B: 1 and 2 only
• C: 2 and 3 only
• D: 1 and 3 only
