Arrange floral/reproductive terms into a logical sequence leading to the product formed after fertilisation: Items: (i) Fruit (ii) Pollen (iii) Corolla (iv) Stamen Choose the correct order that best reflects functional flow within a typical flowering plant.

Introduction / Context:
This question checks conceptual sequencing in basic botany using parts of a flower and the end product of successful reproduction. You are given four terms—pollen, stamen, corolla, and fruit—and asked to arrange them in a logical flow that respects their roles and the overall outcome (fruit formation).

Given Data / Assumptions:

• (ii) Pollen: the male gametophyte that accomplishes fertilisation via pollination.
• (iv) Stamen: the male reproductive organ (anther + filament) associated with pollen.
• (iii) Corolla: the whorl of petals aiding attraction and positioning during pollination.
• (i) Fruit: the fertilised ovary that develops after successful pollination and fertilisation.

Concept / Approach:
We want a coherent functional chain that highlights the role of pollen and the male organ, acknowledges the supportive floral whorl that aids pollination, and ends with the post-fertilisation product (fruit). A compact conceptual path is: recognise the key agent (pollen), pair it with its source/organ (stamen), pass through the pollination interface aided by the corolla (petals), and conclude with fruit formation after fertilisation.

Step-by-Step Solution:

Verification / Alternative check:
Any sequence ending with fruit is sensible only if reproductive steps precede it. Placing fruit before flower parts contradicts plant reproductive chronology. Among the provided options, (ii),(iv),(iii),(i) most succinctly captures “agent → organ → aiding whorl → product”.

Why Other Options Are Wrong:

• (ii),(iii),(iv),(i): Puts the aiding whorl before linking pollen to its organ.
• Sequences placing fruit before any floral component invert causality.
• Other permutations scramble the functional relations among agent, organ, aid, and product.

Common Pitfalls:
Confusing structural nesting (which part surrounds which) with functional flow; here the emphasis is on role-based progression toward fruit formation.

Final Answer:
(ii), (iv), (iii), (i)
