Normal diastolic pressure in young man is about

Options

A. 20 mm Hg
B. 80 mm Hg
C. 100 mm Hg
D. 130 mm Hg

Explanation

### Step-by-Step Solution:

1. **Understanding Diastolic Pressure**: Diastolic pressure is the pressure exerted on the walls of the blood vessels when the heart's ventricles are relaxed. This is an important aspect of blood pressure measurement.

2. **Normal Range for Young Men**: In a healthy young man, the normal diastolic pressure is typically around 80 mm of Hg (millimeters of mercury). This value is a standard reference for assessing blood pressure.

3. **Measurement of Blood Pressure**: Blood pressure, including diastolic pressure, is measured using a sphygmomanometer, which is a device that applies pressure to the arm and measures the pressure in the arteries.

4. **Conclusion**: Therefore, the normal diastolic pressure in a young man is approximately 80 mm of Hg.

### Final Answer:
The normal diastolic pressure in a young man is about **80 mm of Hg**.
