Correct answer: (c) uniform width throughout DNA
Explanation:
Purine always pairs with pyrimidine as it provides stability to the DNA strand because the size of the both differs so the arrangement is in such a way that the larger base forms bond with a smaller base and this makes DNA 2nm thick and this is the complementary rule that provides a uniform width to DNA throughout the length. So the correct option is 'uniform width throughout DNA'.
