Consider that the figure of this question is attached below.

Sugar B is more reactive as it has hydroxyl group at 2' position.

Explanation:

  • The sugar A is deoxyribose sugar present in DNA and lack the hydroxyl group at 2' position.
  • The sugar B is oxyribose sugar present in RNA and shows hydroxyl group at 2' carbon. This hydroxyl group makes it more reactive as this group can acts as a catalyst.
  • The hydroxyl group can react with the other chemical compounds and can be converted into alkoxide ion that breaks the RNA structure.
  • The presence of hydroxyl group makes the RNA as the primitive genetic material as its ability of fast replication and acts as a catalyst.
