Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Rice bran oil is a unique vegetable oil rich in unsaponifiable phytochemical antioxidants, specifically oryzanol and vitamin E isomers.

Step 2: Detailed Explanation:
Refined Rice Bran Oil (extracted from the outer brown layer/aleurone of rice grains) contains high concentrations of natural antioxidants:
1. Vitamin E Complex: Rich in both Tocopherols and Tocotrienols (active fat-soluble antioxidant forms).
2. Gamma-Oryzanol: A potent ferulic acid ester that lowers circulating LDL cholesterol.
