The correct match between item (I) and item (II) is:

• (A) Norethindrone: A synthetic progesterone derivative widely used as an antifertility drug.
  $$\implies \text{(A)} \rightarrow \text{(Q)}$$
• (B) Ofloxacin: A fluoroquinolone derivative used as a broad-spectrum antibiotic.
  $$\implies \text{(B)} \rightarrow \text{(P)}$$
• (C) Equanil: A medication used to manage anxiety and hypertension, classified as a tranquilizer (not an analgesic, but typically pairs with the remaining relevant therapeutic class or specific target line in textbook questions).
  $$\implies \text{(C)} \rightarrow \text{(R)}$$

Conclusion:

Aligning the medicinal categories yields the correct sequence match.
