B. releasing factors
C. mucus
D. sweat

Answer

### Step-by-Step Solution:

1. **Understanding Neurosecretory Cells**: Neurosecretory cells are specialized cells that have characteristics of both nerve cells and secretory cells. They play a crucial role in the nervous system and endocrine system.

2. **Functions of Neurosecretory Cells**: These cells have two primary functions:
- They exhibit electrical activity, which allows them to carry impulses.
- They have a secretory function, which is essential for their role in the body.

3. **Secretory Function**: The main secretory function of neurosecretory cells involves the release of substances into the bloodstream. This is a critical aspect of how these cells communicate with other parts of the body.

4. **What Do They Secrete?**: Neurosecretory cells do not secrete enzymes, mucus, or sweat. Instead, they primarily secrete hormones and releasing factors. These substances are vital for regulating various physiological processes.

5. **Conclusion**: Therefore, the correct answer to the question "Neurosecretory cells secrete" is that they secrete **releasing factors**.
