The correct answer is A. 110/70.
Blood pressure is the force of blood pushing against the walls of your arteries. It is measured in two numbers: systolic pressure and diastolic pressure. Systolic pressure is the pressure when your heart beats, and diastolic pressure is the pressure when your heart is at rest.
Normal blood pressure for adults is less than 120/80 mmHg. If your blood pressure is higher than this, you may have high blood pressure. High blood pressure is a risk factor for heart disease, stroke, and other health problems.
There are several things you can do to lower your blood pressure, including:
- Eating a healthy diet
- Exercising regularly
- Maintaining a healthy weight
- Not smoking
- Limiting alcohol
- Taking medication, if prescribed by your doctor
If you are concerned about your blood pressure, talk to your doctor. They can help you determine if you have high blood pressure and recommend ways to lower it.

- Option A: 110/70 is considered normal blood pressure for adults.
