Solution

The correct option is B Sugar and nitrogen base
In DNA and RNA the nitrogen base is attached to the sugar molecule to form the nucleoside. The sugars deoxyribose and ribose are linked to the nitrogenous base by glycosidic linkage. It is also known as N-glycosidic bond. Thus the correct answer is option C.
