Final answer:
The true statement characterizing the Plateau Phase in Masters & Johnson's sexual response cycle is: B. The body changes resulting from stimulation reaching maximum intensity.
Step-by-step explanation:
In the Plateau Phase, the body's physiological responses are at their peak as a result of continued stimulation, just before reaching the climax of sexual response. This phase involves heightened arousal, where the changes initiated by stimulation—such as increased heart rate, heightened muscle tension, and other physical responses—reach their maximum intensity.
Blood flow to sexual organs increases, contributing to engorgement and heightened sensitivity. Both men and women experience this phase, marked by a plateau in arousal just before the eventual release during orgasm. The body remains in a state of heightened readiness, building tension, and preparing for the release that follows in the orgasmic phase.
Correct answer: B. The body changes resulting from stimulation reaching maximum intensity.
