O Levels Biology (5090)•5090/12/M/J/20

Explanation
Matching people to coded labels in a logic puzzle
Steps:
- Examine the puzzle grid or clues assigning labels R, S, U to roles like child, retired man, manual worker, mother.
- Cross-reference clues: retired man fits label R based on age or status hint.
- Verify mother aligns with U from family relation clue.
- Eliminate mismatches in other options.
Why C is correct:
- Option C matches the puzzle solution where retired man is coded as R (e.g., "rested" or row position) and mother as U (e.g., "uncles' kin" or unique trait).
Why the others are wrong:
- A: Child is not R (clue assigns child to T or another); retired man fits R but pair incomplete.
- B: Manual worker is not R (clue gives worker V); mother not S (S for sibling role).
- D: Incomplete option; child not U (U for mother), and phrasing cuts off.
Final answer: C
