I learnt about this awhile ago! Hold on let me try to remember......
D. Presence of phosphate groups in the backbone of the molecule

Answer:

Option (C).

Explanation:

DNA is present as a genetic material in all the organisms except in case of some viruses. The process of formation of daughter DNA from the parent DNA is known as replication.

The DNA acts as template for the DNA and the RNA molecules. This is because the base pairing of the DNA nitrogenous bases. Cytosine is linked with guanine with three hydrogen bonds whereas adenine is linked with thymine with two hydrogen bonds.

Thus, the correct answer is option (c).
