C. newborn babies
D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Brown Fat:**
- Brown fat, also known as brown adipose tissue, is a type of fat tissue that is primarily involved in thermogenesis (heat production). It is different from white fat, which stores energy.

2. **Identifying the Options:**
- The question provides four options:
a. Blubber of whales
b. Hump of camel
c. Newborn baby
d. None of the above

3. **Analyzing Each Option:**
- **Option A: Blubber of whales** - Blubber is primarily composed of white adipose tissue, which serves as insulation and energy storage.
- **Option B: Hump of camel** - The hump is made up of white fat that serves as an energy reserve.
- **Option C: Newborn baby** - Newborns, especially premature ones, have significant amounts of brown fat, which helps them maintain body temperature and protect against hypothermia.
- **Option D: None of the above** - This option can be ruled out since we have identified a valid option.

4. **Conclusion:**
- Based on the analysis, brown fat is primarily found in newborn babies. Therefore, the correct answer is **C. Newborn baby**.
