Correct answer: DNA contains thymine, while RNA contains uracil.
Explanation: DNA uses thymine (5‑methyluracil), which contributes to greater chemical stability and allows the repair machinery to recognize deaminated cytosine (which would produce uracil) as damage. RNA uses uracil and is generally more short‑lived and suited to transient information transfer and catalysis. The other choices are incorrect or reversed.
