Question

Match List I with List II.

List I	List II
A. Diuretic B. Calcium channel blocker C. β-Blocker D. ACE inhibitor	I. Hydrochlorothiazide II. Atenolol III. Losartan IV. Amlodipine

Choose the correct answer from the options given below:

• A. A-III, B-I, C-II, D-IV
• B. A-I, B-IV, C-II, D-III
• C. A-I, B-IV, C-III, D-II
• D. A-IV, B-I, C-II, D-III

Hint:

Remember: Amlodipine = CCB, Atenolol = $\beta$-blocker, Hydrochlorothiazide = diuretic

Answer 1

The Correct Option is B

Concept:
Different classes of antihypertensive drugs are categorized based on their mechanism of action.

Step 1: Diuretics.

• Hydrochlorothiazide is a thiazide diuretic Thus: \[ A \rightarrow I \]

Step 2: Calcium channel blockers.

• Amlodipine is a commonly used calcium channel blocker Thus: \[ B \rightarrow IV \]

Step 3: Beta-blockers.

• Atenolol is a selective $\beta_1$ blocker Thus: \[ C \rightarrow II \]

Step 4: ACE inhibitor ARB clarification.

• Losartan is technically an ARB (Angiotensin receptor blocker), but often grouped in RAAS inhibitors in exams Thus: \[ D \rightarrow III \]

Step 5: Final mapping.
\[ A\!-\!I,\; B\!-\!IV,\; C\!-\!II,\; D\!-\!III \] \[ \boxed{\text{Correct answer = Option (2)}} \]
