Vasodilators are the correct choice for treating hypertension because they work by relaxing the blood vessels, which helps to lower blood pressure. When blood vessels are dilated, the resistance against which the heart has to pump decreases, leading to improved blood flow and lower pressure in the arteries. This mechanism is particularly useful in managing conditions like hypertension, where reducing the workload of the heart is crucial.

In contrast, vasoconstrictors would have the opposite effect, as they narrow the blood vessels, which increases resistance and subsequently raises blood pressure. Thus, using vasoconstrictors in the treatment of hypertension would be counterproductive, as they would exacerbate the condition rather than alleviate it.

The statement that both types of drugs are equally effective does not hold true in the context of treating hypertension, as their mechanisms act in opposing manners. Similarly, the assertion that neither is effective overlooks the established role of vasodilators as a primary choice in hypertension management.
