A
lipids
B
proteins
C
carbohydrates
D
nucleic acids
Explanation: 

Detailed explanation-1: -So, the correct answer is Lipids.

Detailed explanation-2: -So, the correct answer is Lipids.

Detailed explanation-3: -Macromolecules : Example Question #7 Both lipids (fat) and glycogen (made up of glucose molecules) store energy in animals. Lipids are used for long-term energy storage while glycogen, found in the liver and muscles, is used for short-term energy storage.

Detailed explanation-4: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).

Detailed explanation-5: -Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides.
