The cells that actually release the antibodies are

Options

A. Helper T-cells
B. Cytotoxic T-cells
C. Plasma cells
D. Memory cells

Answer

To answer the question, "The cells that actually release the antibodies are," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Cells Involved in Antibody Production**:
- The immune system has various types of cells, but the primary focus here is on B-cells, which are crucial for the humoral immune response.

2. **Understand the Activation of B-cells**:
- When B-cells encounter an antigen (a substance that triggers an immune response), they become activated. This activation is essential for them to perform their function.

3. **Differentiate Activated B-cells**:
- Once activated, B-cells can differentiate into two main types of cells: Plasma cells and Memory B-cells.

4. **Identify the Function of Plasma Cells**:
- Plasma cells are the specific type of B-cells that produce and secrete antibodies. These antibodies are soluble proteins that help in neutralizing pathogens or marking them for destruction by other immune cells.

5. **Role of Memory B-cells**:
- Memory B-cells are also formed during the activation of B-cells, but their primary function is to remember the specific antigens. They do not secrete antibodies but remain in the body for years to provide a quicker response upon re-exposure to the same antigen.

### Final Answer:
The cells that actually release the antibodies are **Plasma Cells**.
