Answer & Solution

Correct Answer

(A) artificial introduction of sperms of a healthy donor into the vagina

Step-by-step Solution

Detailed explanation

(a) : In artificial insemination technique, the semen of a healthy donor male is collected and is introduced artificially through a flexible polyethylene catheter into the vagina or into uterus called intra uterine insemination \((IUI)\). Best results are obtained when the motile sperm count is more than \(10\) million. The fertilizing capacity of spermatozoa (sperms) is for \(24-48\) hours. The procedure may be repeated \(2-3\) times over a period of \(2 -3\) days.

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.
