Select an option which is true regarding the following two statements labelled Assertion (A) and Reason (R).

A. A satellite is not a planet.

R. Planets do not revolve around other planets.

Assertion (A): A satellite is not a planet — Correct

A satellite, also called a moon, is a space object that moves around a planet. Unlike planets, which go around stars (like the Sun), satellites revolve around planets. This key difference is why satellites are not considered planets.

Reason (R): Planets do not revolve around other planets — Correct

Planets move around stars, not around other planets. For example, in our solar system, all planets orbit the Sun. On the other hand, satellites (moons) orbit planets. This is an important point in defining what makes something a planet.

Both statements are true, and the reason correctly explains the assertion.
So, the right answer is:
"Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'."
