Answer 1

Answer:

A.21st March.

Explanation:

During the spring and autumn equinoxes, i.e. on 21 March and 23 September, the Sun is exactly overhead the Equator and the North and South Poles lie at an equal distance from the Sun. This is the reason days and nights are of equal length throughout the world on these two days.
