Solution

The correct option is B Adenine, Thymine - Purines
There are two kinds of nitrogen-containing bases - purines and pyrimidines.
Purines (adenine and guanine) are two-carbon nitrogen ring bases while pyrimidines (cytosine and thymine) are one-carbon nitrogen ring bases.
Examples of purine are adenine and guanine.
Thymine, cytosine, and uracil are pyrimidines.

So, the correct answer is option B.
