B) two corpora cavernosa and one corpus spongiosum

D) three corpora cavernosa

Accepted Answer

The correct option is two corpora cavernosa and one corpus spongiosum.

The corpus spongiosum is a smaller column of tissue that surrounds the urethra and also becomes engorged with blood during an erection.
