Hint: To answer this question we have to know about lipids. The lipids present in the animal and human body give maximum energy in the metabolic processes. Lipids are made up of hydrocarbons. Vitamin, fat, phospholipids are examples of lipids.

Complete Step by Step Solution:
Fat is a nonpolar substance. It is composed primarily of hydrocarbons. It can be both hydrophobic and lipophilic. Fats are usually flammable and surface active substances. Most of the fats are unsaturated lipids that are present as a solid at room temperature. Both fat and oil are made of glycerol. Fat stores the food and energy of our body. It is a lipid.

Phospholipids are defined as a class of lipids the molecule of which has a hydrophilic "head" which contains a phosphate group and contains two hydrophobic "tails" which are derived from the fatty acids and these are joined by an alcohol residue. Amino acids are the building blocks of protein. This contains one basic amino group and one acidic carboxylic group.

Carbohydrate is a compound of carbon, hydrogen and oxygen. It is an essential constituent of body but not an important essential constituent of diet as it helps in gaining weight. Carbohydrate is present in beans, milk, vegetables etc. It supplies energy to our body.
Thus the correct option are B and D.

Note: On reduction lipid breaks into fat. Fat acts as the energy bank in our body. Fat is solid lipid. It is generally present below the dermis of our skin as subcutaneous fats.
