The correct answer is option 3, Venus.
The period of rotation of a planet refers to the time it takes for the planet to complete one full rotation on its axis. The period of revolution, on the other hand, refers to the time it takes for a planet to orbit around the sun.
Venus is the only planet in our solar system whose period of rotation is longer than its period of revolution. Venus takes about 243 Earth days to complete one rotation on its axis, while it takes approximately 225 Earth days to complete one revolution around the sun. This means that a day on Venus is actually longer than a year on Venus.
This unique characteristic of Venus is due to its slow and retrograde (backward) rotation, which is opposite to the direction in which it orbits the sun.
Therefore, the correct answer is Venus.
