A
Amount of ATP
B
Function of cell
C
Size of cell
D
DNA
Explanation: 

Detailed explanation-1: -Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Detailed explanation-2: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

Detailed explanation-3: -Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules.

Detailed explanation-4: -Answer and Explanation: All the cells in a body have the same DNA (except for a few types of cells that don’t have DNA) because they all originated from the same fertilized ova. This original cell divided through mitosis and the process continues the entire time the body is alive.
