All the options are correct.

Explanation:

In the given question, the model of the DNA is not given but assuming that the DNA of Eukaryotes would have been provided therefore based on the previous knowledge this can be answered.

The DNA molecule is made up of two strands of nucleotide monomers which are composed of four types of nitrogenous bases (A, G, T, C), a 5 carbon sugar and a phosphate group.

The sugar and phosphate group forms the backbone of the DNA molecule and the nitrogenous bases are present inside of the backbone which is joined to the Complementary base pair via hydrogen bonds. 2 hydrogen bonds are formed between A and T and 3 hydrogen bonds are formed between G and C.

Thus, all the options are correct.
