Which of the following is NOT associated with Aryabhata?

The correct answer is Option 4- Spoke about elaborate surgical procedures

Spoke about elaborate surgical procedures is NOT associated with Aryabhata.

Aryabhata was a mathematician and astronomer who lived in India during the 5th century CE. He made significant contributions to both fields, including developing a place value system that included the number zero, calculating the circumference of the Earth, and proposing a heliocentric model of the solar system. However, he did not write about surgery or medicine.

The other three options are all associated with Aryabhata:

• He stated that day and night were caused by the rotation of the Earth on its axis, which was a revolutionary idea at the time.
• He developed a scientific explanation for eclipses, which he correctly identified as being caused by the Moon passing in front of the Sun (for a solar eclipse) or the Earth passing in front of the Moon (for a lunar eclipse).
• He found a way of calculating the circumference of a circle, which he approximated to be 3.1416.

The correct answer is Option
