Limbs of human and frog is example of A)Homologous organsB)Analogous organsC)Both A and BD)Artificial selection

The correct answer is A) Homologous organs.

Here’s the detailed explanation:

Homologous organs are those that have a similar structure and origin but may serve different functions in different species. In the case of the limbs of humans and frogs, both species have forelimbs that are structurally similar, with similar bones (such as the humerus, radius, ulna in humans, and the equivalent bones in frogs). This similarity arises because both species share a common evolutionary ancestor.

Although the functions of the limbs differ (humans use their arms for grasping and manipulating objects, while frogs use their forelimbs primarily for jumping and supporting the body), the underlying structure is similar, which makes them homologous organs.

Analogous organs (option B) refer to organs that serve similar functions in different species but have different structural origins. An example would be the wings of a bird and the wings of a bat; both are used for flying but have different structural designs and evolutionary origins.

Artificial selection (option D) refers to the intentional breeding of organisms with desired traits, which is unrelated to the comparison of limb structures in humans and frogs.

Therefore, the correct answer is A) Homologous organs.
