As we move away from the sun in the Solar system :
Question

As we move away from the sun in the Solar system :

A.

Time taken to complete one orbit around sun by planets increases.

B.

Time taken to complete one orbit around sun by planets decreases.

C.

Time taken to complete one spin on its own axis by planets increases.

D.

Time taken to complete one spin on its own axis by planets remains constant.

Correct option is A

As we move away from the sun in the Solar system, the time taken to complete one orbit around the sun by planets increases. This is because the planets farther from the sun have to travel a longer distance to complete one orbit. The orbital period of a planet is directly proportional to the semi-major axis of its orbit, which is the average distance between the planet and the sun.
The time taken to complete one spin on its own axis by planets does not follow a consistent pattern. Some planets, such as Venus, spin very slowly, while others, such as Jupiter, spin very quickly. The rotation period of a planet is not related to its distance from the sun.
Here is a table of the orbital periods and rotation periods of the planets in the Solar system:

Planet
Orbital Period (Earth years)
Rotation Period (Earth days)
Mercury
0.24
58.6
Venus
0.62
243.0
Earth
1.00
0.99
Mars
1.88
1.03
Jupiter
11.86
9.9
Saturn
29.46
10.8
Uranus
84.01
-17.0
Neptune
164.79
16.1

As you can see, there is no correlation between the orbital period and the rotation period of a planet.
