Final Answer :
C
Explanation :
Viagra increases blood flow specifically to the penis, which helps to achieve and maintain an erection. It does not increase whole body blood pressure or the activity of the PDE-5 enzyme, and it does not decrease blood flow to the penis or reduce the amount of seminal fluid.
