Answer 1

Answer: (A)

In this particular sentence, we can understand that the the blank specifies something which is happening which means that we are going to use present continuous tense. The present continuous tense is a grammatical tense that can be used to describe when an action happened, or may happen. So, we would be using present continuous tense for the given blank. The present continuous tense usually ends in an "-ing".

"leaving" is the correct continuous form now since it is in present "are" should be used before the continuous form.

Option A is correct
