Final answer:
The sperm are suspended in seminal fluid, a critical component of semen mainly produced by the seminal vesicles, prostate gland, and bulbourethral glands in the male reproductive system. The correct option is b. Seminal Fluid
Step-by-step explanation:
The sperm are suspended in seminal fluid, which is a fluid produced by several glands in the male reproductive system. Semen, the fluid that is ejaculated during sexual climax, contains sperm which are haploid cells, consisting of a flagellum for motility, a neck that contains the cell's energy-producing mitochondria, and a head that contains the genetic material.
Semen is a mixture of sperm (about 5 percent of the total volume) and fluids from accessory glands, such as the seminal vesicles, prostate gland, and bulbourethral glands, which contribute the majority of the semen's volume and provide the necessary environment to control pH and supply nutrients to the sperm. The correct option is b. Seminal Fluid
