Correct option is D
Correct Answer: (d)
Explanation:
Tendril of Cucurbita and thorn of Bougainvillea arise from modifications of stem, so they are homologous organs, not analogous.
Information Booster:
Analogous organs → same function, different origin.
Homologous organs → different functions, same origin.
Wings of insect and bat → analogous (different structure, same function).
Fins of fish and whale → analogous due to convergent evolution.
Tendril & thorn share common developmental origin → homologous.
Additional Information (Incorrect Options):
(a), (b), (c) → All represent analogous structures formed through convergent evolution.
