Beta-blockers are primarily used to manage hypertension (high blood pressure) and various heart-related conditions, making this the correct choice. These medications work by blocking the effects of adrenaline on the beta-adrenergic receptors in the heart, leading to a decrease in heart rate and cardiac output. This can help to lower blood pressure and reduce the workload on the heart, which is particularly beneficial for individuals with conditions such as chronic heart failure, angina, and arrhythmias.

Additionally, beta-blockers are effective in preventing migraines and reducing anxiety symptoms during stressful situations, but their main applications remain in cardiovascular health. It's important to note that while other choices present relevant areas of healthcare, they do not align with the primary uses of beta-blockers. For instance, alleviating allergies is typically managed with antihistamines, treating infections requires antibiotics, and cholesterol levels are generally managed with statins or other lipid-lowering agents rather than beta-blockers.
