C Zygote is collected from female donor and transferred to the fallopian tube to facilitate zygote formation in the recipient.
D Zygote is collected from a female donor and transferred to the uterus of recipient.

Verified Solution

Answer & Solution

Correct Answer

(B) Ova collected from a female donor are transferred to the fallopian tube to facilitate zygote formation in the recipient.

Step-by-step Solution

Detailed explanation

(B) Ova collected from a female donor are transferred to the fallopian tube to facilitate zygote formation in the recipient.,
If a woman is not able to release ova for fertilisation and further development, then Gamete Intra Fallopian Transfer (GIFT) is utilized female. In this technique, the ovum from a donor female can be transferred to the fallopian tube of this woman, so that fertilisation takes place inside the body (in vivo).

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.
