The correct answer is A. 120 mm and 80 mm.
Systolic pressure is the pressure in the arteries when the heart beats. Diastolic pressure is the pressure in the arteries when the heart is at rest between beats.
A healthy adult’s blood pressure should be below 120/80 mmHg. If your blood pressure is higher than this, you may have high blood pressure, also known as hypertension.
High blood pressure is a serious condition that can lead to heart disease, stroke, and other health problems. If you have high blood pressure, it is important to work with your doctor to control it.
Option B is incorrect because the systolic pressure is too high. Option C is incorrect because the diastolic pressure is too low. Option D is incorrect because both the systolic and diastolic pressures are too low.
