The correct answer is B. 120/80.
Blood pressure is the force of blood pushing against the walls of your arteries. It is measured in millimeters of mercury (mm Hg). The top number, or systolic pressure, is the pressure when your heart beats. The bottom number, or diastolic pressure, is the pressure when your heart is at rest between beats.
Normal blood pressure is less than 120/80 mm Hg. If your blood pressure is between 120/80 and 139/89 mm Hg, you have prehypertension. If your blood pressure is 140/90 mm Hg or higher, you have high blood pressure.
High blood pressure is a major risk factor for heart disease, stroke, kidney disease, and other health problems. If you have high blood pressure, it is important to work with your doctor to control it.
Option A is incorrect because 80/120 is a higher blood pressure than 120/80.
Option C is incorrect because 80/110 is a higher blood pressure than 120/80.
Option D is incorrect because 110/90 is a higher blood pressure than 120/80.
