Official UPSC Answer KeyUPSC Prelims 2000 • Science and Technology

Correct Answer: Option (D) — oil has very low erucic acid content

Concept & Option Breakdown

Standard Reference Verified

Canola (acronym for Canadian oil, low acid) refers to selectively bred cultivars of rapeseed/mustard (Brassica napus and Brassica rapa) that have very low levels of erucic acid (< 2% in the oil) and low levels of glucosinolates in the meal, eliminating the cardiovascular and nutritional risks associated with traditional high-erucic-acid rapeseed oil.

Elimination Heuristic & Exam Approach

The defining scientific differentiator of Canola compared to wild rapeseed is the elimination of toxic erucic acid ('low acid').
