Answer:
The correct answer is use for selfish purposes.
Step-by-step explanation:
The word in bold would be exploit, in which case we can come to the conclusion that movie theaters take advantage of one's senses by filling the air with popcorn scent.
This is a selfish purpose since the aim of this action is to get an individual to buy more product by taking advantage of the appetizing popcorn scent.
We can conclude that the other answers don't denote the word exploit in this sentence since a movie theater generally wants more money spent so it wouldn't try to offend, anger, annoy or irritate its clients.
