Answer

**Step-by-Step Solution:**

1. **Understanding Adipose Tissue**: Adipose tissue is a type of connective tissue that stores fat in the body. It is primarily found beneath the skin (subcutaneous) and serves various functions, including energy storage and insulation.

2. **Types of Adipose Tissue**: There are two main types of adipose tissue:
- **Brown Adipose Tissue (BAT)**: This type contains multiple small lipid droplets and a high number of mitochondria, making it metabolically active. It is primarily involved in heat generation, especially in infants and hibernating mammals.
- **White Adipose Tissue (WAT)**: This type has a single large lipid droplet and fewer mitochondria, making it less metabolically active. Its main function is to store energy in the form of fat.

3. **Analyzing the Statement**: The statement claims that "White adipose tissue is predominant in infants and has several small lipid droplets and numerous mitochondria."
- This is incorrect because white adipose tissue is characterized by a single large lipid droplet and is not predominant in infants. Instead, brown adipose tissue is predominant in infants and has the features mentioned in the statement.

4. **Analyzing the Reason**: The reason states that "White fat is metabolically less active."
- This is correct because white adipose tissue does indeed have fewer mitochondria and is less metabolically active compared to brown adipose tissue.

5. **Conclusion**:
- The statement is incorrect, while the reason is correct. Therefore, the correct answer is that the statement is incorrect, but the reason is correct.

**Final Answer**: The correct option is D: The statement is incorrect, but the reason is correct.
