Solution
The correct options are
B Uracil and Cytosine are pyrimidines
D Adenine and Thymine are purines
Nitrogenous bases are broadly of two types - purines and pyrimidines. Adenine and guanine are the purines, while thymine and cytosine are the pyrimidines of DNA. In RNA, uracil replaces thymine, whereas all the other bases remain the same.
