The Correct Option is A

Solution and Explanation

Identifying the components of DNA: DNA contains nitrogenous bases like purines (adenine and guanine) and pyrimidines (thymine and cytosine). The structural components shown in the options correspond to these bases.
Option A represents adenine (A), a purine base found in DNA.
Option D represents guanine (G), another purine base found in DNA.
Thus, the correct answer is option (1).
