Which most directly causes hypertension ? a. lack of blood flow to the heart b. a weakening of a blood vessel wall c. excessive force of blood pumping d. injury to heart muscle

The answer is C.) Excessive force of blood pumping

Hypertension is the condition of having abnormally high blood pressure.

It can't be A, since hypertension is the condition of highly pressurized blood flow, which typically means a lot of blood is flowing.

It isn't B, since the wall of the blood vessel doesn't effect hypertension.

And finally, it can't be D, since an injury to the heart would typically make it weaker: not too strong.

Thus, your answer is C.
