B
erectile tissues
C
scrotum tissues

Explanation: 

Detailed explanation-1: -The corpus cavernosa and the corpus spongiosum make reproduction possible. The blood that fills these spongy tissues makes your penis hard enough to penetrate the vagina during sexual intercourse.

Detailed explanation-2: -Corpora Cavernosa The penile erectile tissue, specifically the cavernous smooth musculature and the smooth muscles of the arteriolar and arterial walls, plays a key role in the erectile process.

Detailed explanation-3: -During sexual arousal, nerve messages begin to stimulate the penis. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand and creating an erection.
