Arrange the biological life-cycle stages into a meaningful chronological order, starting at the beginning and moving to the outcome: (A) Plant, (B) Seed, (C) Fruit, (D) Seedling. Choose the natural seed → seedling → plant → fruit progression.

Introduction / Context:Sequencing questions based on natural processes reward everyday scientific knowledge. In flowering plants, the usual life-cycle proceeds from a seed that germinates into a seedling; the seedling grows into a mature plant, which then bears flowers and fruit. Recognizing this order allows an unambiguous mapping from biological reality to a list of symbols.

Given Data / Assumptions:

• Stages: Seed (B), Seedling (D), Plant (A), Fruit (C).
• We assume a standard angiosperm life-cycle perspective for general reasoning items.

Concept / Approach:The logic is developmental: a dormant propagule (seed) germinates to an early growth stage (seedling), which matures into the full plant. Only a mature plant produces fruit as a reproductive output. Hence the correct chain is Seed → Seedling → Plant → Fruit.

Step-by-Step Solution:Start: Seed (B).Next: Seedling (D) by germination.Then: Mature Plant (A) through growth.Finally: Fruit (C) after flowering/reproduction.So the order is (B), (D), (A), (C).

Verification / Alternative check:Any order placing fruit before plant contradicts reproduction. Any order placing seedling before seed is impossible. The selected sequence uniquely matches the growth pathway.

Why Other Options Are Wrong:

• Orders with plant before seedling ignore germination.
• Fruit placed before plant violates maturity requirements.
• “None of these” is not valid since a correct order exists.

Common Pitfalls:Interchanging “seedling” and “plant” or overlooking that fruit is an outcome of maturity.

Final Answer:(B), (D), (A), (C)
