B

C
Thorns of Bougainvillea and tendrils of Cucurbita
D

Answer
Gills of prawn and lungs of man
Explanation
Solution
The organs with similar functions but different in structural details and origin are known as analogous organs.
- The wings of bats are analogous to the wings of pigeons. This is because the basic structure of mammalian wings is different from the wings of the bird but has similar functions.
- Similarly, the gills of prawns and the lungs of man, both are respiratory organs yet they have very different basic structures.
Hence, option B) Gills of prawn and lungs of man is the correct answer.
