During the resolution phase of the sexual response cycle, people are most likely to experience a rapid decrease in physiological arousal ifa) they have just experienced orgasm. b) they have not used contraceptives. c) their refractory period is unusually short. d) their sexual interaction has not resulted in conception.

A) they have just experienced orgasm.

Explanation:

The resolution phase of the sexual response cycle begins shortly after individuals have just experienced orgasm and is characterized by the reversal of the arousal process when the body recovers its resting state prior to arousal. In this phase, there is a rapid decrease in physiological arousal, where the body replaces the usual levels of respiration, heartbeat and muscle contraction that changed during the previous phases of the sexual response cycle.
