Show answer and explanation

Correct answer: (C) P–2, Q–3, R–4, S–1

Explanation

The historical associations are influenza A–amantadine (P–2), fungus–fluconazole (Q–3), malaria parasite Plasmodium–artemisinin (R–4), and Mycobacterium–isoniazid (S–1). These give C. This is an exam matching question about drug targets, not present-day clinical treatment advice; resistance can affect actual use.
