These organic molecules are used by the body to store the genetic code.
A
Carbohydrates
B
Lipids
C
Proteins
D
Nucleic Acids
Explanation: 

Detailed explanation-1: -DNA is the molecule that stores our genetic information (Figure below). The single-stranded RNA is involved in making proteins. ATP (adenosine triphosphate), known as the “energy currency” of the cell, is also a nucleic acid. A model representing DNA, a nucleic acid.

Detailed explanation-2: -The organic molecules that are nucleic acids are DNA and RNA. DNA is the genetic material of the cell. It is the ultimate source of instructions for coding for proteins. RNA has several functions in the cell.

Detailed explanation-3: -In nature, just two closely related nucleic acids, DNA and RNA, function as repositories and carriers of genetic information. They therefore are the molecular embodiment of biological information.

Detailed explanation-4: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
