A. Both Statement I and Statement II are correct
B. Statement I is correct and Statement II is incorrect
C. Statement I is incorrect and Statement II is correct
D. Both Statement I and Statement II are incorrect

Answer: D

Explanation:
Both statements are incorrect. A test tube baby does not develop entirely inside a test tube; only fertilization occurs outside the body in a laboratory. After fertilization, the embryo is transferred into the uterus where normal development occurs. In IVF-ET, fertilization happens outside the female body, not inside.

Options:
A. Both Statement I and Statement II are true
B. Both Statement I and Statement II are false
C. Statement I is correct but Statement II is false
D. Statement I is incorrect but Statement II is true

Answer: A
Explanation: Both statements are correct. ICSI is a highly specialized form of IVF where a sperm is directly injected into an egg. Artificial insemination helps in cases where natural fertilization is difficult by placing sperm directly into the female reproductive tract.
