A normal resting blood pressure is approximately:

A120/80 mmHg (systolic / diastolic)
B160/100 mmHg (a hypertensive value)
C80/40 mmHg (a hypotensive value)
D200/120 mmHg (extreme hypertension)
Answer & Solution
Correct answer: A. 120/80 mmHg (systolic / diastolic)
Normal resting BP ≈ 120/80 mmHg (systolic over diastolic). ≥140/90 = hypertension. ≤90/60 = hypotension. Measured with a sphygmomanometer.
