Answer
Correct Answer: C
Explanation
Introduction / Context:We are to find the maximum (tallest) in a partially ordered set of four items using concise comparative statements.
Given Data / Assumptions:
- A is only higher than D ⇒ A > D and A < (B, C).
- B is shorter than C but higher than A ⇒ C > B > A.
- All heights are distinct.
Concept / Approach:Combine the inequalities: C sits above B, which sits above A, which sits above D. Therefore, C is the tallest and D is the shortest.
Step-by-Step Ordering:
From “A only higher than D” we place A above D and below both B and C.From “B shorter than C but higher than A,” place B between C and A.Final chain: C > B > A > D.Verification / Alternative check:Every original relation is satisfied by C > B > A > D.
Why Other Options Are Wrong:
- A, B, D: Not the maximum in the derived chain.
- None of these: A specific correct choice exists (C).
Common Pitfalls:Misinterpreting “only higher than D” (it fixes A exactly one place above D and below the other two).
Final Answer:C
