To make a mountain of a molehill is nothing else _________ sheer fooli
Right Answer is: A
Option A is the correct choice. “Else” takes “but” with it. i.e. “nothing else but sheer foolishness.” “Than” is used to introduce second element in comparison. “Rather” is used to indicate one’s preference and “unless” is a conjunction used to join a condition.
Example: Religion is nothing else but love to God and man.
