The normal blood pressure of a man is generally considered to be 80/120 mm Hg. Blood pressure is measured in millimeters of mercury (mm Hg) and consists of two numbers. The first number, called systolic pressure, represents the pressure in the arteries when the heart beats and pumps blood. The second number, called diastolic pressure, represents the pressure in the arteries when the heart is at rest between beats.

Option 1, 80/120 mm Hg, falls within the normal range for blood pressure. The systolic pressure of 80 mm Hg indicates a healthy contraction of the heart, and the diastolic pressure of 120 mm Hg indicates a relaxed state of the heart. It is important to note that blood pressure can vary slightly from person to person and may also change throughout the day based on factors like stress, activity level, and overall health.
