Final Answer:

Step-by-step explanation:
According to Masters & Johnson, the Excitement Phase in the sexual response cycle is characterized by the initiation of sexual arousal. This phase begins with external or internal stimuli that trigger a physiological response, including increased heart rate, respiration, and blood pressure.
During the Excitement Phase, individuals experience heightened arousal as a result of sexual stimulation. The body responds to these stimuli by preparing for sexual activity, with noticeable physiological changes. The increase in heart rate, respiration, and blood pressure signifies the body's readiness for further stages of the sexual response cycle. This phase is crucial in understanding the progression of sexual response and lays the foundation for subsequent stages leading towards orgasm. The correct option is D. Initiated by whatever is stimulating to the person; heart, respiration, and blood pressure rates increase."
