The correct option is B 120/80 mm Hg
Blood pressure refers to the force of the body’s blood pushing against the inner walls of the blood vessels, especially the arteries. Each time the heart contracts, it pumps blood into the arteries.
A healthy blood pressure reading should be lower than 120/80 mmHg. Normal blood pressure is less than 120 mmHg systolic and 80 mmHg diastolic, and may vary from 90/60mmHg to 120/80mmHg. A blood pressure of 140/90 mmHg or higher indicates high blood pressure.
