B
16, 18
C
24, 36
D
100, 200
Explanation: 

Detailed explanation-1: -The Sun has a north and south pole, just as the Earth does, and rotates on its axis . However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles.

Detailed explanation-2: -The outer layers of the Sun exhibit differential rotation: at the equator the surface rotates once every 25.4 days; near the poles it’s as much as 36 days. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. Similar effects are seen in the gas planets.

Detailed explanation-3: -Astronomers say that the sun rotates once every 27 to 31 days, rather than give an exact number, because the sun’s rotation period is not constant across its entire surface. The sun is not a solid body like Earth; it is a massive ball of gas and plasma. As a result, different parts of the sun rotate at different rates.

Detailed explanation-4: -Sun-Like Stars’ Equators Spin Up To 2.5 Times Faster than Their Poles, Say Astronomers. Our Sun rotates faster at its equator than at its poles. This process is known as differential rotation and is seen in the motion of sunspots.
