Answer:
The correct answer is D. inflated and make
Explanation:
The first option is not possible because the action is in the present simple not in the present continuous. The second option presents a possibility, so we can discard that option. The third option is in the past simple, so is not possible to use it there. and the last one uses an infinitive verb but the verb "to make" needs to be conjugated there so it is not possible to use the infinitive. The most accurate is the fourth answer.
