Macromolecule composed of amino acids
A
Lipid
B
Nucleic acid
C
Carbohydrate
D
Protein
Explanation: 

Detailed explanation-1: -The macromolecules made of amino acids are: (a) proteins. Proteins are folded polypeptides that are composed of amino acid monomers covalently linked together by peptide bonds.

Detailed explanation-2: -It is composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, and carbohydrates) and large non-polymeric molecules such as lipids, nanogels and macrocycles.

Detailed explanation-3: -Proteins are macromolecular polypeptides-i.e., very large molecules (macromolecules) composed of many peptide-bonded amino acids. Most of the common ones contain more than 100 amino acids linked to each other in a long peptide chain.
