The correct option is A seminal fluid
Semen consists of spermatozoa in seminal plasma, which provides a nutritive medium for conveying the sperm to the endocervical mucus. The components of semen are obtained from the testes, prostate, epididymid, vas deferens. bulbourethral glans, and urethral glands.
Seminal vesicles produce fructose, citric acid, and other nutrient substances as well. These substances are of great nutritive value to the sperms until one of the sperm fertilises the ovum.
Tunica vaginalis is the outermost protective covering of the testes.
