Step-by-step explanation:
The most commonly prescribed medication for a pregnant woman with chronic hypertension is beta-blockers option (C). Beta-blockers are a class of antihypertensive medications that work by blocking the effects of adrenaline on the beta receptors in the body. By doing so, they reduce the heart rate and decrease the force of contraction, leading to a decrease in blood pressure.
Beta-blockers are commonly used to manage chronic hypertension in pregnant women. They help to reduce blood pressure by blocking the effects of certain stress hormones like adrenaline.
