Step 1: Understanding the Concept
ZIFT stands for zygote intra-fallopian transfer.
It is an assisted reproductive technology used to treat infertility.
Step 2: What is transferred
The ovum is fertilised outside the body (in vitro). The zygote, or an early embryo with up to 8 blastomeres, is placed in the fallopian tube.
Step 3: Compare the options
Transfer of an embryo into the uterus is IUT, transfer of ova is GIFT, and placing sperms in the female tract is artificial insemination. So only option C describes ZIFT.
Final Answer:
ZIFT transfers an externally fertilised ovum (zygote) into the fallopian tube.
\[ \boxed{\text{(C) }\text{externally fertilized ovum to the fallopian tube of the female.}} \]
