Choice A is wrong because beta blockers do not block angiotensin II receptors, but rather beta-adrenergic receptors, which are involved in the sympathetic nervous system. Beta blockers reduce heart rate and blood pressure by inhibiting the effects of adrenaline and noradrenaline

Choice B is wrong because calcium channel blockers do not block angiotensin II receptors, but rather calcium channels, which are involved in the contraction of smooth muscle cells. Calcium channel blockers relax blood vessels and lower blood pressure by reducing the influx of calcium into the cells

Angiotensin II receptor blockers (ARBs) block the binding of angiotensin II to its receptors on blood vessels and adrenal glands, preventing its vasoconstrictive and aldosterone-stimulating effects

Choice D is wrong because direct acting vasodilators do not block angiotensin II receptors, but rather act directly on the smooth muscle cells of blood vessels, causing them to relax and dilate. Direct acting vasodilators lower blood pressure by decreasing peripheral resistance
