Correct Answer
(D) Gene therapy
Solution & Explanation
Answer: (D) Gene therapy Solution: Gene therapy inserts genes into a person's cells and tissues to treat a hereditary disease. It corrects a gene defect either by replacing a defective allele with a functional one or by gene targeting, which involves gene amplification — exactly the process described in the stem. NCERT Reference: Ch 10, p.186, line 45 — "gene targeting which involves gene amplification"
