Concept:
Drugs are classified based on their pharmacological action.
Step 1: Identify each drug.
(a) Dimetapp:
Used for allergy relief → blocks histamine
\[
\Rightarrow \text{Antihistamine (v)}
\]
(b) Furacine:
Used to prevent infection in wounds
\[
\Rightarrow \text{Antiseptic (iii)}
\]
(c) Phenelzine:
Used in treatment of depression
\[
\Rightarrow \text{Antidepressant (i)}
\]
(d) Aspirin:
Used as pain reliever
\[
\Rightarrow \text{Analgesic (ii)}
\]
(e) Norethindrone:
Used in birth control pills
\[
\Rightarrow \text{Antifertility (iv)}
\]
Step 2: Write matching.
\[
(a)-(v), \quad (b)-(iii), \quad (c)-(i), \quad (d)-(ii), \quad (e)-(iv)
\]
Step 3: Match with options → Option (D)
Final Conclusion:
\[
\boxed{\text{Correct matching is option (D)}}
\]
