Answer:

A. DNA molecules

Step-by-step explanation:

DNA molecules contain the nitrogenous bases of adenine, thymine, guanine, and cytosine.

RNA molecules have the same bases, except they do not have thymine.

In RNA, thymine is replaced with uracil.

So, since only DNA has thymine, the correct answer is A. DNA molecules
