A. ‌ ‌Para-ventricular‌ ‌nucleus‌ ‌
B. Supra-optic‌ ‌nucleus‌
C. ‌Median‌ ‌eminence
D. ‌Pars‌ ‌distalis‌

Answer

### Step-by-Step Solution:

1. **Identify the Hypothalamus**: The hypothalamus is a small region of the brain located below the thalamus. It plays a crucial role in hormone production and helps to regulate various bodily functions, including temperature regulation, thirst, hunger, sleep, and emotional activity.

2. **Understand the Role of the Paraventricular Nucleus (PVN)**: The paraventricular nucleus is a specific region within the hypothalamus. It consists of a group of neurons that are activated by physiological changes in the body, such as stress.

3. **Link PVN to Sweat Secretion**: The paraventricular nucleus is specifically responsible for physiological sweat secretion. This means that when the body undergoes certain physiological changes, such as an increase in temperature or stress, the PVN activates mechanisms that lead to the production of sweat.

4. **Differentiate from Other Nuclei**: Other regions of the hypothalamus, such as the supraoptic nucleus, have different functions. The supraoptic nucleus is involved in modulating autonomic responses and producing hormones like oxytocin and vasopressin, but it is not primarily responsible for physiological sweat secretion.

5. **Conclusion**: Therefore, the specific region of the hypothalamus responsible for physiological sweat secretion is the **Paraventricular Nucleus (PVN)**.
