Answer 1

The correct answer is:

B. His heart beats faster and his breathing rate increases.

In a stressful situation, such as almost getting into an accident, the body activates the "fight or flight" response, which is part of the sympathetic nervous system. This results in an increase in heart rate, faster breathing, and other physiological changes to prepare the body to react to the perceived threat.
