• B. Wings of Grasshopper and Crow
• C. Pectoral fins of Fish and forelimbs of Horse
• D. Gills of Fish and lungs of Rabbit

Answer 1

The correct option is C Pectoral fins of Fish and forelimbs of Horse

Homologous organs :
Homologous organs have the same basic structural plan but perform different functions.
For example:

• Pectoral fins of fish and forelimbs of horse show similarity in structure but perform different functions due to differences in habitats.

Analogous organs :
Analogous organs have different origin and basic structure but perform the same function.
Examples:

• Wings of insects and bats are structurally different but perform the same function of flying.
• Gills of fishes and lungs of rabbits differ in the basic structure but both play a role in breathing.
• Wings of grasshopper and crow are different in structure but perform the same function of flying.

Final answer :
(C) Pectoral fins of Fish and forelimbs of Horse
