Answer:

a. sympathetic

Explanation:

The function of the sympathetic nervous system is to control the reaction of a person's response to fear. The response can be fight-flight-or-freeze.

Here, Harry is nervous about driving. In order to cope with his nervousness, his sympathetic nervous system causes his heart and pulse to race. His nervous system is trying to decide whether to be in a state of fight-flight-or-freeze.

Hence, the statement here is referring to the sympathetic nervous system.
