Plant life cycle and human use: Arrange the following in a logical cause–effect chain starting from reproduction: A) Seed → C) Plant → B) Fruit → D) Food (consumed by humans) Choose the correct sequence.

Introduction / Context:
This is a straightforward life-cycle flow. A seed germinates into a plant, which bears fruit; fruits are edible and become food for humans. The sequence should reflect this biological and practical order.

Given Data / Assumptions:

• A) Seed germinates.
• C) Plant develops.
• B) Fruit is produced by the plant.
• D) Food represents human consumption of the fruit.

Concept / Approach:
Follow biological causality: reproductive unit → organism → product → human use.

Step-by-Step Solution:
A → C → B → D.Hence ACBD.

Verification / Alternative check:
Placing fruit or food before seed/plant contradicts biology.

Why Other Options Are Wrong:
They start from a derivative (fruit/food) rather than the cause (seed).

Common Pitfalls:
Swapping fruit and seed; remember fruit is the plant’s product, not its precursor.

Final Answer:
ACBD
