Match Assisted Reproductive Technologies in column I with their process in column II and select the correct option

	Column I		Column II
a.	ZIFT	i.	Single sperm cell is injected directly in cytoplasm of an ovum
b.	GIFT	ii.	Fertilized egg is transferred to fallopian tube for further development
c.	ICSI	iii.	Sperms are introduced into the Uterus
d.	IUI	iv.	Ova and sperms are directly injected into regions of the oviduct where fertilization occurs.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
