Read the following passage and answer the next five questions:
The reproductive cycle of female primates is called menstrual cycle. Menstrual cycle starts only after attaining sexual maturation (puberty). Generally, during ovulation only one ovum is released per menstrual cycle. The cyclical changes in the ovary and the uterus during menstrual cycle are induced by changes in the levels of pituitary and ovarian hormones. After coitus, sperms are transported to the junction of the isthmus and ampulla, where the sperm fertilises the ovum leading to formation of a diploid zygote.
The female external genitalia include:
(A) Mons pubis
(B) Hymen
(C) Mammary ducts
(D) Clitoris
(E) Cervix
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A), (B) and (D) only
(A) Mons pubis — Correct. It is a cushion of fatty tissue covered by skin and pubic hair.
(B) Hymen — Correct. It is the membrane that partly covers the opening of the vagina.
(C) Mammary ducts — Incorrect. These ducts are inside the mammary glands (breasts). They carry milk from the alveoli towards the nipple. The breasts are accessory organs, not external genitalia.
(D) Clitoris — Correct. It is a tiny finger-like structure above the urethral opening.
(E) Cervix — Incorrect. The cervix is the narrow lower part of the uterus. It lies inside the body, so it is not part of the external genitalia.

NCERT Extract:
The Female Reproductive System – “… The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris (Figure 2.3a). Mons pubis is a cushion of fatty tissue covered by skin and pubic hair. The labia majora are fleshy folds of tissue, which extend down from the mons pubis and surround the vaginal opening. The labia minora are paired folds of tissue under the labia majora. The opening of the vagina is often covered partially by a membrane called hymen. The clitoris is a tiny finger-like structure which lies at the upper junction of the two labia minora above the urethral opening.”
