Answer 1

The correct option is A 120/80 mm Hg

Blood pressure is the pressure of blood within the arteries. It is produced primarily by the contraction of the heart muscle. The normal human blood pressure is 120/80 mm of Hg.

Blood pressure is measured using two numbers. The first number, called systolic blood pressure, measures the pressure in the blood vessels when the heart beats. The second number, called diastolic blood pressure, measures the pressure in the blood vessels when the heart rests between beats.
