• A. Tail of a kangaroo
• B. Wing of a butterfly
• C. Tail fin of a fish
• D. Arm of a human

Answer 1

The correct option is D Arm of a human

If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous. The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different in purpose, but they are similar structurally and share common traits.

So, the correct option is 'Arm of a human'.
