Walking into a class that he had foolishly ignored for a month, Roy discovers that an exam is scheduled for that session. As part of his panic, which of the following happens?

A) Roy's sympathetic nervous system becomes aroused.
B) Roy's parasympathetic nervous system becomes aroused.
C) Roy's hindbrain shuts down to conserve energy.
D) Roy's midbrain shuts down to conserve energy.

Roy's sympathetic nervous system would be activated in a situation of panic, as it prepares the body for the "fight or flight" response. This includes increased heart rate, blood pressure, and adrenaline secretion. The parasympathetic nervous system is responsible for the body's "rest and digest" functions and would not be activated in a panicked state. The hindbrain and midbrain are responsible for basic survival functions such as breathing and heart rate, and would not shut down to conserve energy in a panicked state.
