The correct answer is (a) Heart attack.
Beta-blockers are a type of medication that is used to treat a variety of conditions, including high blood pressure, angina, and heart failure. They work by blocking the effects of the hormone adrenaline, which can cause the heart to beat faster and the blood vessels to narrow. This can help to reduce the risk of heart attack and stroke.
Beta-blockers are also used to treat other conditions, such as anxiety, tremor, and migraine headaches. However, they should not be used by people with certain conditions, such as asthma or chronic obstructive pulmonary disease (COPD).
(b) Enlargement of Prostate gland is a condition called benign prostatic hyperplasia (BPH).
