• C. Diuretic
• D. Antifungal

Hint:

Answer 1

The Correct Option is A

Concept:
Propranolol is a drug used in cardiovascular disorders.

Step 1: Beta blockers block beta adrenergic receptors.

Step 2: Propranolol blocks both \(\beta_1\) and \(\beta_2\) receptors.

Step 3: Blocking \(\beta_1\) receptors reduces heart rate and force of contraction.

Step 4: This helps in hypertension, angina, and arrhythmias.

Step 5: Therefore, propranolol is classified as a beta blocker. \[ \boxed{\text{Beta blocker}} \]
