• B. Analogous organs only
• C. Both A and B
• D. Homologous and vestigial organs

Answer 1

Answer: (D)

Homologous and vestigial organs

"Homologous organs" have the same fundamental structure but are different in functions These organs follow the same basic plan of organization during their development. But in the adult condition, these organs are modified to perform different functions as an adaptation to different environments. "Vestigial organs" are present in reduced form and do not perform any function in the body but correspond to the fully developed functional organs of related animals.

So, the correct answer is "Homologous and vestigial organs".
