Explanation:
The equator is the imaginary line that divides the earth into two equal halves, The distance from the equator to both the poles are equal. The equator passes through the 0° latitude. The region in and around the equator receives the maximum amount of sunlight emitted from the sun.
This equator is the line of longest latitude and its total length is nearly 24,901.6 miles.
Hence, the correct answer is option (B).
Answer: Osmosis is the diffusion of water molecules, from a regions of higher concentration to a region of lower concentration, through a selectively permeable membrane. Osmosis is directly dependent upon the concentrations of the solutes : a dilute solution will contain a higher concentration of water molecules, while a concentrated solution contains a low concentration of water molecules. As, a result of this the level on more concentrated side will rise and cell will get swell. On the other hand the level on less concentrated side the cell will shrink. When concentration is the same on both the sides of the membrane , the movement of water molecules will be the same in both directions. At this point, the net exchange of water will become zero and there will be no changes in the liquid levels.

ummmm I would definitely love to help you but this is a different language that I dunno how to read so I can't answer it sorry
