Official UPSC Answer KeyUPSC Prelims 1996 • Science and Technology

Correct Answer: Option (C) — spraying hormones on flowers

Concept & Option Breakdown

Standard Reference Verified

Seedless fruits develop through induced parthenocarpy (fruit development without prior pollination and fertilization). Spraying unpollinated flower buds with plant growth hormones—specifically auxins or gibberellins—stimulates the ovary wall to enlarge and develop into a seedless fleshy fruit.

Elimination Heuristic & Exam Approach

Seedlessness in fruits (parthenocarpy) is universally regulated and induced using phytohormones (auxins/gibberellins).
