Correct answer: B. Test tube baby
- A. Cloning
- B. Test tube baby
- C. Both (A) and (B)
- D. In vivo fertilization
Explanation
Test tube babies term refers to a baby conceived through in vitro fertilization (IVF), where an egg is fertilized by sperm outside the body, typically in a laboratory dish or test tube. The resulting embryo is then implanted into the uterus for gestation and development. So, while this term is commonly used, it's not entirely accurate as the fertilization doesn't actually occur in a test tube, but rather in a petri dish or similar container.
