Granules which strain by basic dye found in which cell `:-`

Options

A. Monocyte
B. Plasma cell
C. Reticular cell
D. Mast cell

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about granules that can be stained by a basic dye and which type of cell contains these granules.

2. **Identify the Cell Types**: The options provided are:
- Monocytes
- Plasma cells
- Reticular cells
- Mast cells

3. **Classify the Cells**:
- **Monocytes**: These are agranulocytes and do not have granules, so they cannot be stained by a basic dye.
- **Plasma Cells**: These are derived from B lymphocytes and are also agranulocytes, meaning they lack granules and cannot be stained by a basic dye.
- **Reticular Cells**: These are fibroblast-like cells and do not contain granules, thus they cannot be stained by a basic dye either.
- **Mast Cells**: These are a type of basophil found in connective tissue. Basophils contain granules that can be stained by basic dyes.

4. **Conclusion**: Since mast cells are essentially basophils located in tissues and can be stained by basic dyes due to the presence of granules, the correct answer is **Mast Cells**.

5. **Final Answer**: The granules which stain by basic dye are found in **Mast Cells**.
