Type of fat found in foetuses and infants is  

Options

A. red adipose tissue
B. white adipose tissue
C. brown adipose tissue
D. all the above

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the type of fat found in fetuses and infants. We need to identify the specific type of adipose tissue that is prevalent in these early stages of life.

2. **Types of Adipose Tissue**: There are two main types of adipose tissue:
- **White Adipose Tissue (WAT)**: This type primarily stores energy.
- **Brown Adipose Tissue (BAT)**: This type is involved in generating body heat.

3. **Function of Brown Adipose Tissue**: Brown adipose tissue is particularly important in newborns and infants because it helps to generate heat through a process called thermogenesis. This is crucial for maintaining body temperature in infants who are unable to regulate their body heat as effectively as adults.

4. **Eliminating Incorrect Options**:
- **Red Adipose Tissue**: This is not a recognized type of adipose tissue in the context of human physiology.
- **White Adipose Tissue**: While it is a type of fat, it is primarily for energy storage and does not play a significant role in thermoregulation in infants.
- **All of the Above**: Since red adipose tissue is not a valid option, this choice is also incorrect.

5. **Conclusion**: The type of fat found in fetuses and infants is **Brown Adipose Tissue (BAT)**, which is essential for heat generation.

### Final Answer:
The type of fat found in fetuses and infants is **Brown Adipose Tissue (BAT)**.
