Official UPSC Answer KeyUPSC Prelims 2011 • Science and Technology

Correct Answer: Option (A) — To make it pest-resistant

Concept & Option Breakdown

Standard Reference Verified

Bt-brinjal is genetically engineered by incorporating the Cry1Ac gene from the soil bacterium Bacillus thuringiensis. The expressed endotoxin provides built-in resistance against lepidopteran insect pests, particularly the Fruit and Shoot Borer (Leucinodes orbonalis).

Elimination Heuristic & Exam Approach

'Bt' always refers to the bacterium Bacillus thuringiensis, which produces insecticidal crystal proteins, indicating pest-resistance technology.
