In arousal theory, people are said to have a(n) _________ level of tension.

A) ultimate
B) lower
C) optimal
D) high

Arousal theory suggests that individuals have an optimal level of tension that they seek to maintain. This level varies from person to person and different activities or situations may require different levels. If the level is too high, individuals may experience stress or anxiety. If the level is too low, individuals may become bored or disinterested. Therefore, the optimal level of tension is the most appropriate answer.
