Solution

The correct option is A DNA
Thymine is a pyrimidine (molecular formula, $C_{5} H_{6} N_{2} O_{2}$ ) found primarily within DNA in the form of a deoxynucleotidyl residue, paired with adenine. Thymine is also found in trace quantities within transfer RNA. Chemically, thymine can be considered to be a derivative of uracil, and is sometimes referred to as 5-methyluracil.
