Answer

### Step-by-Step Solution:

1. **Understanding the Question**:
The question asks for the characteristics of primitive monkeys that are relevant to the evolution of humans. We need to analyze the given options to determine which characteristic aligns with human evolution.

2. **Analyzing the Options**:
- **Option A: Thumb parallel to fingers**: This is incorrect because humans have opposable thumbs, which allow for a greater range of motion and grip.
- **Option B: 32 teeth**: This is correct. Both primitive monkeys and modern humans typically have 32 teeth, although the jaw size differs.
- **Option C: Prehensile tail**: This is incorrect as modern humans do not have a prehensile tail; this feature is more common in some primates for grasping.
- **Option D: Flat nose**: This is also incorrect because modern humans have a more pronounced nose structure compared to primitive monkeys.

3. **Identifying the Correct Answer**:
Based on the analysis, the characteristic that aligns with the evolution of humans from primitive monkeys is **Option B: 32 teeth**.

4. **Conclusion**:
The correct answer to the question is that the characteristic of primitive monkeys which is in the direction of evolution of man is **32 teeth**.
