could anyone confirm me the answere of that question and what about option A because the size of the earth is bigger than moon soooo. wht will be the bst option
the best and correct answer is a) .size of the earth in relation to that of moon.

this question is more of a commen sence rather of guessing.moon is much smaller than earth. The penumbra and umbra formed by moon is also small because of the small size of moon in comparison to that of formed by earth in case of lunar eclipse where total lunar eclipse is possible.
hope the issue is resolved
