Step 1: Understanding the Question.
Four schedules, FF, F3, V and Y, need to be matched to four descriptions: ophthalmic preparation standards, umbilical tape standards, patent and proprietary medicine standards, and clinical trial requirements.
Step 2: Key Approach.
Start from the schedule that is easiest to place with certainty, then use it to filter the four options down before checking the rest.
Step 3: Detailed Explanation.
Schedule Y is the schedule most closely tied to clinical research, it lays down the requirements and guidelines a new drug must satisfy for trial approval, so 4 should match [Q]. Checking the given options, only 1-[S], 2-[R], 3-[P], 4-[Q] keeps this pairing.
Next, Schedule FF governs standards for ophthalmic preparations such as eye drops, so 1 should match [S], which the surviving option already satisfies.
That leaves Schedule F3, which sets sterility standards for umbilical tapes used in newborn care, matching [R], and Schedule V, which covers standards of patent and proprietary medicines, matching [P]. Both fall in line with the same option once Y and FF are fixed.
Step 4: Final Answer.
The correct match is 1-[S], 2-[R], 3-[P], 4-[Q].
