Answer:
Molecule 3
Explanation:
DNA contains Deoxyribose, Phosphate, and 4 bases: Adenine(A), Thymine(T), Guanine(G), and Cytosine(C)
Molecule three contains Deoxyribose, Phosphate, and Guanine, while the others do not.
RNA contains ribose, which is why Molecule 2 is out of the question.
DNA does not contain glucose, henceforth marking Molecule 1 incorrect.
Molecule 4 may seem correct, but recall that DNA contains Deoxyribose, Phosphate, and a base, in this case Guanine(G). This answer contains no Deoxyribose.
