- Adenine
- Thymine
- Uracil
- Cytosine
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The given structure has a pyrimidine ring with two keto groups (at positions 2 and 4) and one NH group — this is the characteristic structure of Uracil.
Thymine is similar but has a methyl group at position 5.
Thymine is similar but has a methyl group at position 5.
