Detailed explanation-1: -Vegetable oils are mainly triacylglycerols (92–98%), polar lipids (phospholipids and galactolipids), monoacylglycerols, diacylglycerols, and minor amounts of free fatty acids and polyisoprenoids.

Detailed explanation-2: -Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds.

Detailed explanation-3: -Answer and Explanation: Vegetable oils, such as corn oil, belong to the B) lipid class of organic substances. This is because vegetable oils are primarily composed of triglycerides, which are lipids made up of three individual fatty acids covalently linked to a glycerol backbone.

Detailed explanation-4: -Dietary lipids are primarily oils (liquid) and fats (solid). Commonly consumed oils are canola, corn, olive, peanut, safflower, soy, and sunflower oil. Foods rich in oils include salad dressing, olives, avocados, peanut butter, nuts, seeds, and some fish. Fats are found in animal meat, dairy products, and cocoa butter.

Detailed explanation-5: -Vegetable oils are a group of fats that are derived from some seeds, nuts, cereal grains, and fruits. It is important to understand that not all of these vegetable oils are liquid oils at ambient temperatures.
