Answer: 4. Flipper of Whale

Homologous organs share the same basic anatomical plan (here the forelimb bones) but may differ in function. A bird's wing and a whale's flipper are both modified vertebrate forelimbs, so they are homologous.

Shark dorsal fin and moth wing: analogous (different origin, similar function).
Rabbit hind limb: a hindlimb, not a forelimb.
