	Column I		Column II
A.	Hyaluronidase	(i)	Acrosomal reaction
B.	Corpus luteum	(ii)	Morphogenetic movements
C.	Gastrulation	(iii)	Progesterone
D.	Capacitation	(iv)	Mammary gland
E.	Colostrum	(v)	Sperm activation

• A. A - (v), B - (ii), C - (iv), D - (i), E - (iii)
• B. A - (i), B - (iii), C - (ii), D - (v), E - (iv)
• C. A - (iii), B - (ii), C - (v), D - (iv), E - (i)
• D. A - (i), B - (ii), C - (iii), D - (iv), E - (v)

Answer 1

The correct option is B A - (i), B - (iii), C - (ii), D - (v), E - (iv)

Acrosomal reaction involves the release of Hyaluronidase as a part of the enzymes required for penetration into the ovum membrane and fertilization subsequently. Corpus luteum secretes large amounts of progesterone which is essential for the maintenance of the endometrium. Gastrulation refers to the development of the blastocyst with germ layers into a gastrula by means of morphogenetic movements or gradient based movement for developing into different parts of the embryo. Capacitation is the process of sperm activation when changes take place in the sperm membrane and make it possible for it to fertilize the egg. Colostrum is the milk produced by lactation in the mammary glands during the initial few days after delivery.

So, the correct option is 'A - (i), B - (iii), C - (ii), D - (v), E - (iv)'.
