An example of homologous organs is
(a) Our arm and a dog’s foreleg (b) Our teeth and an elephant’s tusks
(c) Potato and runners of grass
(d) All of the above

Answer – (d)

Homologous organs have the same origin as each of the above organs but different functions.

The term “homologous organs” refers to organs from different species that have a similar basic structure but perform diverse tasks.

For example, a whale’s flippers, a frog’s forelimbs, and a man’s have the same basic structures but perform different functions, which is why they are called homologous organs.
