Explanation / Answer

Ans ( a ) Nitrogenous base A ( adenine ) pairs with Thymine T with two hydrogen bond and Guanine G is bonded with Cytocine C with three Hydrogen bonds. As a result purine comes opposite to pyrimidine. This makes uniform distance between two strands of the helix and also create stability.
