The correct answer is 1 is Deoxyribose, 2 is Guanine and 3 is Cytosine. If u see the structure, attachment and arrangement it is easily identified. Only Guanine and Cytosine can bind with each other and adenine and thymine can bind with each other. Guanine binds with cytosine via triple bond and here we can see that triple bond is present. Thus it is deduced from the structure and bonding that 1 is Deoxyribose, 2 is Guanine and 3 is Cytosine.
