A planet's rotation determines the length of its day and its revolution determines the length of its year. A day on Earth is 24 hours and a year on Earth is 365 days. In contrast to Earth, a day on Venus is longer than a year on Venus. Which is the best reason for why this is so?

Step-by-step explanation:

The speed of rotation of Venus is slower than that of Earth that is why a day on Venus is longerthan Earth's day. Whereas, Venus is closer to sun than Earth, this means Venus trajectory of revolution is smaller than that of Earth.Therefore, a year on Venus is shorter than Earth's year.
