Official UPSC Answer KeyUPSC Prelims 2007 • Science and Technology

Correct Answer: Option (B) — Fallopian tube

Concept & Option Breakdown

Standard Reference Verified

In human reproduction, fertilization of the ovum by a spermatozoon normally occurs within the Fallopian tube (oviduct), specifically in the ampullary region (ampullary-isthmic junction). The resulting zygote begins cleavage while traveling towards the uterine cavity for subsequent implantation.

Elimination Heuristic & Exam Approach

Fertilization occurs in the Fallopian tube (specifically ampulla), while implantation occurs in the endometrium of the uterus.
