Answer: (B) National Parks. Answer: (B) National Parks.
- A.In vitro fertilization
- B.National Parks✓
- C.Micropropagation
- D.Cryopreservation
Correct Answer
(B) National Parks
Solution & Explanation
Answer: (B) National Parks. Solution: Ex situ conservation involves taking threatened species out of their habitat and using techniques like in vitro fertilization, micropropagation (tissue culture) and cryopreservation - all listed in NCERT as ex situ methods. National Parks protect organisms within their natural habitat, making them in situ, so they are not an ex situ method. NCERT: NCERT Class XII Biology, Ch 13 Biodiversity and Conservation, p.225, lines 22-25: "Now gametes of threatened species can be preserved in viable and fertile condition for long periods using cryopreservation techniques, eggs can be fertilised in vitro, and plants can be propagated using tissue culture methods."
