Find the odd one cut

Options

A. Trunk of an elephant and hand of a chimpanzee
B. Ginger and sweet potato
C. Wings of bat and insect
D. Nails of human belings and claws of a cat

Answer

To solve the question "Find the odd one cut," we will analyze the provided options based on the concepts of homologous and analogous organs.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Homologous Organs**: These are organs that have the same basic structure and origin but may serve different functions. They arise from a common ancestor.
- **Analogous Organs**: These are organs that serve similar functions but have different structures and origins. They do not share a common ancestor.

2. **Analyzing the Options**:
- **Option 1**: Trunk of an elephant and hand of a chimpanzee.
- The trunk of an elephant is a modification of soft tissue (flesh, fat, nerves) while the hand of a chimpanzee is a bony structure (forelimb). These have different origins, making them analogous organs.

- **Option 2**: Ginger and sweet potato.
- Ginger is a modification of a stem, while sweet potato is a modification of a root. These also have different origins, making them analogous organs.

- **Option 3**: Wings of a bat and wings of an insect.
- The wings of a bat are a modification of a forelimb (bony structure), while the wings of an insect are made of cuticle (non-bony). These have different origins, making them analogous organs.

- **Option 4**: Nails of human beings and claws of a cat.
- Both nails and claws are made of keratin protein and serve a similar function (protection and support). They share a similar structure and origin, making them homologous organs.

3. **Identifying the Odd One Out**:
- The first three options (1, 2, and 3) are examples of analogous organs, while option 4 is an example of homologous organs. Therefore, option 4 is the odd one out.

### Conclusion:
The answer to the question "Find the odd one cut" is **Option 4: Nails of human beings and claws of a cat**.
