The proteins which are found in anti bodies in blood are

Options

A. histones
B. albumins
C. globulins
D. scleroproteins

Answer

To answer the question about the proteins found in antibodies in blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Antibodies**: Antibodies are proteins produced by the immune system in response to foreign substances known as antigens (like viruses, bacteria, or parasites).

2. **Identify the Type of Proteins**: Antibodies are specifically classified as immunoglobulins. They are a type of protein that plays a crucial role in the immune response.

3. **Examine the Options**: The options given are:
- Histone
- Albumin
- Globulin
- Scleroproteins

4. **Analyze Each Option**:
- **Histone**: These are proteins associated with DNA and do not function as antibodies.
- **Albumin**: This is a protein found in blood plasma but is not involved in the immune response.
- **Globulin**: This is a category of proteins that includes antibodies (immunoglobulins).
- **Scleroproteins**: These are structural proteins and do not play a role in immune response.

5. **Select the Correct Answer**: Since antibodies are a type of globulin, the correct answer is **Globulin**.

### Final Answer:
The proteins which are found in antibodies in blood are **Globulin**.
