Fat with adipocytes which are metabolically inactive are  

Options

A. multilocular
B. alocular
C. solid
D. monolocular

Answer

To answer the question "Fat with adipocytes which are metabolically inactive are," we need to analyze the options provided: multi-locular, a-locular, solid, and mono-locular.

### Step-by-Step Solution:

1. **Understand Adipocytes**: Adipocytes are fat cells that store energy in the form of fat. They can be classified into different types based on their structure and function.

2. **Identify Types of Fat**:
- **Multi-locular Fat**: This type of fat is known as brown fat. Brown adipose tissue contains multiple lipid droplets and is metabolically active, meaning it generates heat and burns calories. Therefore, it cannot be the answer since we are looking for metabolically inactive fat.

- **A-locular Fat**: This term is not commonly used in the context of adipose tissue classification and does not refer to a specific type of fat. Hence, it is unlikely to be the correct answer.

- **Solid Fat**: This term generally refers to fats that are solid at room temperature (like butter). While solid fats can be metabolically inactive, this term does not specifically describe the type of adipocytes.

- **Mono-locular Fat**: This refers to white adipose tissue, which contains a single large lipid droplet. Mono-locular adipocytes are typically considered metabolically inactive compared to brown fat cells.

3. **Conclusion**: Based on the analysis, the correct answer is **mono-locular**, as it describes fat with adipocytes that are metabolically inactive.

### Final Answer:
Fat with adipocytes which are metabolically inactive are **mono-locular**.
