Arousal primarily involves parasympathetic stimulation of pelvic nerves, not sympathetic stimulation of sacral nerves. The other options (A, B, C, E) are indeed factors that contribute to arousal, with nitric oxide playing a crucial role in vasodilation, the integrity of the sacral spinal cord being essential for nerve signal transmission, sufficient blood hydrostatic pressure being necessary for an erection, and parasympathetic stimulation being a key trigger for the process.
