Options

A. `{:("Type of connective tissue ","Location"),("Adipose tissue","Beneath the skin"):}`
B. `{:("Type of connective tissue ","Location"),("Areolar tissue","Beneath the skin"):}`
C. `{:("Type of connective tissue ","Location"),("Dense connective tissue","Tendons"):}`
D. `{:("Type of connective tissue ","Location"),("Specialised connective tissue","Cartilage"):}`

Answer

To solve the question regarding the connective tissue that contains abundant fibroblasts, macrophages, and mast cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Key Components**: The question mentions three specific types of cells found in the connective tissue: fibroblasts, macrophages, and mast cells.

2. **Understand the Functions of These Cells**:
- **Fibroblasts**: These are the most common cells in connective tissue and are responsible for producing collagen and other fibers. They play a crucial role in maintaining the structural framework of tissues.
- **Macrophages**: These are immune cells that help in the defense against pathogens and in the removal of dead cells and debris.
- **Mast Cells**: These cells are involved in inflammatory responses and release histamine and other chemicals during allergic reactions.

3. **Recall Types of Connective Tissue**: There are various types of connective tissues such as loose connective tissue, dense connective tissue, adipose tissue, and specialized connective tissues. Among these, we need to identify which type contains all three cell types mentioned.

4. **Identify Areolar Connective Tissue**: Areolar connective tissue is a type of loose connective tissue that is characterized by a loose arrangement of fibers and a variety of cell types, including fibroblasts, macrophages, and mast cells. It serves as a binding tissue that holds organs in place and provides support.

5. **Confirm the Answer**: Since the question specifically asks for the connective tissue that has an abundance of fibroblasts, macrophages, and mast cells, the correct answer is **Areolar Connective Tissue**.

6. **Select the Correct Option**: Based on the information provided, the option that corresponds to Areolar Connective Tissue is option B.

### Final Answer:
The connective tissue having the presence of abundant fibroblasts, macrophages, and mast cells is **Areolar Connective Tissue** (Option B).
