Venus is the only planet which takes more time for rotation than revolution.

Explanation:

Rotation and Revolution:
Rotation refers to the spinning or turning of a planet on its axis, which determines the length of its day. Revolution, on the other hand, refers to the orbital motion of a planet around the Sun, which determines the length of its year.

The Relationship between Rotation and Revolution:
In most cases, the time taken for a planet to complete one rotation on its axis is roughly the same as the time taken for it to complete one revolution around the Sun. This means that the length of a planet's day is usually equal to its year. However, there are exceptions to this rule.

Mercury, Venus, Earth, and Mars:
- Mercury: Mercury is the closest planet to the Sun and it has a rotation period of about 59 Earth days. However, its revolution period is only about 88 Earth days. This means that Mercury takes longer to rotate on its axis than it does to complete one orbit around the Sun.
- Venus: Venus is the second planet from the Sun and it has a rotation period of about 243 Earth days. Its revolution period is approximately 225 Earth days. Therefore, Venus takes longer to rotate on its axis than it does to complete one orbit around the Sun.
- Earth: Earth takes approximately 24 hours to complete one rotation on its axis, which determines the length of a day. Its revolution period is about 365.25 days, which determines the length of a year. Therefore, Earth's rotation and revolution periods are roughly equal.
- Mars: Mars has a rotation period of about 24.6 Earth hours and a revolution period of about 687 Earth days. This means that Mars takes longer to rotate on its axis than it does to complete one orbit around the Sun.

Conclusion:
Out of the given options, Venus is the only planet that takes longer to rotate on its axis than it does to complete one orbit around the Sun. Therefore, the correct answer is option 'B' - Venus.
