Psychologists have used four perspectives in their efforts to explain motivation. these include an emphasis on instincts, optimum arousal, a hierarchy of motives, and:

a) 360-degree feedback.
b) refractory periods.
c) drive reduction.
d) basal metabolic rate.
e) fixed behavior patterns

C

Explanation: The correct answer is letter C, Drive Reduction. When a need that must be satisfied is presented, tension appears because our body functions with homeostasis (to be balanced) and this need causes an imbalance. This tension creates a drive to reduce it and it plays an important role in motivation; for example: if we are hungry, that generates a need which must be satisfied so we are driven to search for food, that way we are motivated to reduce that drive.
