• A. They are homologous organs
• B. They are analogous organs
• C. Bat and mole had different ancestors
• D. Bat and mole had a common ancestor

Answer 1

Answer: (A), (D)

Bat and mole had a common ancestor

$\bullet$ Homologous organs are organs of different animals which shows structural similarity but perform different functions.
$\bullet$ Organs like wings of bat, claw of a mole, hand of a man, leg of a cheetah have common pattern of arrangement of bones but their functions are different.
$\bullet$ All these animals are evolved from the common ancestors. Hence, this type of evolution is also known as divergent evolution.
