• A. Vestigial organs
• B. Analogous organs
• C. Homologous organs
• D. Exoskeleton

Answer 1

The correct option is C

Homologous organs

The correct option is C:

Explanation of the correct option:

1. Homologous organs are organs that have a similar structure but perform different functions in different animals.
2. Although the anatomical structure of the organ is similar the function differs.
3. The wings of birds, hands of humans, and wings of bats are examples of homologous organs. All the structures are similar but they perform different functions.
4. The wings of birds and bats are used for flying, and humans use their forelimbs for writing, eating, and holding objects.

Explanation of the incorrect options:

Option A:

Vestigial organs are organs that were once functioning but have become useless or have reduced their function owing to evolutionary changes.

Option B:

1. Analogous organs are organs that have different anatomy but perform similar functions and have different origins.
2. An example of an analogous organ is the wings of the insect and the wings of the bird.

Option D:

An exoskeleton is the rigid outer covering of the body that protects the body of an organism from any damage.

Final answer: Wings of birds, bats, and human hands are examples of homologous organs.
