In which sentence is the word 'exiting' a gerund? a. we were stuck in the parking lot behind all the exiting cars b. after visiting hours, people were exiting as quietly as possible. c. check the smoke detector before exiting. d. after the concert, all the guests were exiting.

The correct answer is C.

A gerund is a verb ending in -ing that functions as a noun.

In "Check the smokes detector before exiting" exiting is not functioning as the continuous form of the verb "to exist" but as a noun.

A is wrong because "parking" and "exiting" are both functioning as adjectives.

B is wrong because "visiting" is functioning as an adjective, and "exiting" comes after "were" and therefore is a verb.

C is wrong because of the same reason as the second part of B. "Were exiting" is a verb.
