| List - I | List - II |
| (A) Antifertility drug | (I) 1% solution of phenol |
| (B) Tranquilizers | (II) Novestrol |
| (C) Analgesics | (III) Noradrenalin |
| (D) Disinfectant | (IV) Aspirin |
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
Drugs are classified by their therapeutic action; each class is matched with the substance named for it:
(A) Antifertility drug — This matches (II) Novestrol. Birth control pills contain a synthetic progesterone derivative together with an estrogen derivative, ethynylestradiol (novestrol).
(B) Tranquilizers — This matches (III) Noradrenalin. Tranquilizers include the antidepressants, which act on noradrenaline, a neurotransmitter that affects mood: a low level of noradrenaline causes depression, and antidepressant drugs (such as iproniazid and phenelzine) inhibit the enzyme that breaks it down. Of the given substances, noradrenalin is the one linked with tranquilizers.
(C) Analgesics — This matches (IV) Aspirin. Aspirin is a non-narcotic analgesic; it relieves pain by inhibiting the synthesis of prostaglandins.
(D) Disinfectant — This matches (I) 1% solution of phenol. The same substance can act as an antiseptic or a disinfectant depending on its concentration: 0.2% phenol is an antiseptic, while 1% phenol is a disinfectant.
Shortcut: The pair (A)–(II) appears only in Option (3).
