• A. Two days.
• B. Four days.
• C. Five days.
• D. None of the above.

Answer 1

The correct option is A Two days.

There are two days on equinox .As the earth revolves around the sun , the equator receives perpendicular rays on two days in a year. This condition occurs on 21st March and 23rd September. On these days, both the poles are at the same distance from the sun.This is called equinox.
