Which one of the following planets takes the same number of days for rotation and revolution?

A. Mars

B. Venus

C. Mercury

D. Jupiter

Answer: Option B

Solution(By Examveda Team)

Venus is the planet that takes nearly the same number of days for rotation as it does for revolution around the Sun. This phenomenon is known as synchronous rotation or tidal locking. As a result, Venus rotates on its axis very slowly and in the opposite direction compared to most other planets. It takes about 243 Earth days for Venus to complete one rotation on its axis, and it also takes about 225 Earth days to complete one orbit around the Sun. This means that a day (rotation) on Venus is longer than its year (revolution). Therefore, the correct answer is Option B, which is Venus.
