Option b

Detailed Solution

Step 1: Defining RNA Bases — Ribonucleic acid (RNA) contains the bases Adenine, Guanine, Cytosine, and Uracil.

Step 2: Excluding DNA Specific Bases — Thymine is found in DNA but is replaced by Uracil in RNA strands.

Step 3: Result Selection — Among the options, only the structure of Uracil (Option b) is found in RNA. Correct option is (b).

Key Point: This replacement is one of the three primary structural differences between DNA and RNA.
