  1. A
    Nucleoside - Uracil
  2. B
    Cholesterol - Guanine
  3. C
    Amino acid -
  4. D
    Nucleotide - Adenine

Solution & Step-by-step Explanation

The structure consists of a pentose sugar (ribose) attached to a nitrogenous base. This category is a Nucleoside. If a phosphate group was attached, it would be a nucleotide. If the base "X" is Uracil, the nucleoside is uridine.Shutterstock Explore
