Option 1 which is  "It provides greater resistance to photochemical mutation," is a solid justification for using thymine instead of uracil to boost DNA stability. Thymine possesses a methyl group that Uracil does not, which protects it against photochemical damage such as the creation of thymine dimers produced by UV light. Thymine contributes to the integrity of the DNA molecule and protects it against mutations produced by external causes. Hence option 1 is the correct answer.
