Difficulty: Medium
Correct Answer: (C), (B), (D), (A)
Explanation:
Introduction / Context:
Life-cycle ordering problems can start at different points but must preserve a coherent biological loop. A seed germinates to a seedling, which grows into a plant that produces fruit, which carries seeds. The set of choices here does not include the straightforward B→D→A→C in that order; thus we select the option that maintains a valid cyclic logic from a different starting point.
Given Data / Assumptions:
Concept / Approach:
A biologically consistent loop is: Seed → Seedling → Plant → Fruit → (back to Seed). Even if the sequence begins at Fruit, proceeding to Seed, then Seedling, then Plant still preserves causality when read cyclically.
Step-by-Step Solution:
Chosen order: Fruit (C) → Seed (B) → Seedling (D) → Plant (A).This corresponds to harvesting fruit that contains seeds, seeds germinating into seedlings, and seedlings maturing into plants.
Verification / Alternative check:
Rotating the start of a cycle is acceptable if the causal direction is preserved. C→B→D→A matches the same loop as B→D→A→C, only with a different starting point.
Why Other Options Are Wrong:
Common Pitfalls:
Insisting on a single fixed start when the question allows any meaningful order; overlooking the fruit→seed containment relationship.
Final Answer:
(C), (B), (D), (A)
