Solution
The correct option is C Homologous organs
The organs which have the same fundamental structure but are different in functions are called homologous organs. These organs follow the same basic plan of the organization during their development. But in the adult condition, these organs are modified to perform different functions as an adaptation to different environments. The forelimbs of cat, lizard, whale, and bat have the same basic structural plan. in each case, the fore-limb consists of humerus, radio-ulna, carpals, metacarpals, and digits. The skeletal parts of the forelimbs of all these animals have different shapes and functions. In lizard, they are used for walking, in the cat for running, in a whale for swimming and in the bat for flying.
