Answer

To solve the question "The blubber is formed by," we will analyze the options provided and determine which one correctly identifies the composition of blubber.

### Step-by-Step Solution:

1. **Understanding Blubber**:
- Blubber is a thick layer of fat found beneath the skin of aquatic mammals such as whales and seals. It serves as insulation against cold temperatures.

2. **Analyzing the Options**:
- **Option 1**: Fibers, matrix, mass, cells, fat, cells, and macrophages.
- This describes dense irregular connective tissue, which is not the correct composition of blubber.
- **Option 2**: Osteon or osteocyte.
- Osteocytes are bone cells, indicating specialized connective tissue (bone). This is incorrect for blubber.
- **Option 3**: Fat-laden cells (adipocytes).
- Adipocytes are specialized cells that store fat. This is the correct composition of blubber.
- **Option 4**: Blood smear.
- Blood is a fluid connective tissue and does not relate to the composition of blubber.

3. **Identifying the Correct Answer**:
- Based on the analysis, **Option 3** (fat-laden cells or adipocytes) is the correct answer as it directly describes the composition of blubber.

### Final Answer:
The blubber is formed by **fat-laden cells (adipocytes)**.
