B Correct answer
Explanation

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are antioxidants specifically added to fats and oils in foods to prevent oxidation. Oxidation causes fats to become rancid, developing off-flavors and odors. These compounds work by interrupting the free-radical chain reactions that cause lipid breakdown. They do not affect sugars, colors, or artificial sweeteners.
