Fill up the blanks in the following paragraph by selecting the correct option.
(i) are the primary female sex organs that produce (ii) and (iii). Each primary sex organ is about (iv) in length and is connected to the pelvic wall and uterus by (v).

  1. (i)-Testes, (ii)-sperms, (iii)-hormones, (iv)-4-5 cm, (v)-ligaments

  2. (i)-Ovaries, (ii)-oogonia, (iii)-follicles, (iv)-2-4 cm, (v)-muscles

  3. (i)-Ovaries, (ii)-ovum, (iii)-hormones, (iv)-2-4 cm, (v)-ligaments

  4. (i)-Testes, (ii)-sperms, (iii)-testosterone, (iv)-8-9 cm, (v)-muscles
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ovaries are the primary female sex organs that produce the female gamete/germ cell ovum and several steroid hormones such as estrogen and progesterone also called ovarian hormones. Each ovary is about 2-4 cm in length and is connected by ligaments to the pelvic wall and the uterus.  Each ovary is whitish in colour and located alongside the lateral wall of the uterus and the other side points downwards attached to the uterus via the ovarian ligament.

So, the correct option is '(i)-Ovaries, (ii)-ovum, (iii)-hormones, (iv)-2-4 cm, (v)-ligaments'.
