Option-1: Both A and R are individually true and R is the correct explanation of A.

This option states that both the assertion (A) and the reason (R) are true, and the reason correctly explains the assertion. According to the assertion, the Equatorial regions bulge outwards by about 21 kilometers compared to the Poles, and the reason given is that Earth`s slow rotation reduces the effect of gravity around the Equator. However, this is not entirely correct. While it is true that the Equatorial regions bulge outwards, the reason provided is not the correct explanation for this phenomenon. The bulging of the Equatorial regions is primarily caused by the centrifugal force generated due to the Earth`s rotation, which opposes the force of gravity. Therefore, option-1 is incorrect.

Option-2: Both A and R are individually true, but R is not the correct explanation of A.

This option acknowledges that both the assertion (A) and the reason (R) are true. The Equatorial regions do bulge outwards, but the reason provided is not the correct explanation for this phenomenon. Hence, option-2 is the correct answer.

Option-3: A is true, but R is false.

This option states that the
