(b) II and IV
(c) III and IV
(d) I and III
Correct Answer: (d) I and III
Explanation:
Potato and sweet potato are analogous organs in plants and animals.
The wings of insects and the wings of bats are analogous organs in animals.
Analogous organs are superficially similar, anatomical dissimilar, and perform the same functions. Analogous organs are not inherited from their ancestors.
They are developed in unrelated species because of convergent evolution and adaptation to a similar environment.
For example, wings in birds, bats and insects; fins in penguins and fishes are analogous organs.
