• D. cytosine 5’-monophosphate

Answer: (B)

Verified step by step guidance

1. Identify the components of the nucleotide structure in the image. The structure consists of a phosphate group, a pentose sugar, and a nitrogenous base.
2. Examine the nitrogenous base attached to the sugar. In this image, the base is cytosine, which is characterized by the presence of an amino group (NH2) and a carbonyl group (C=O) on the pyrimidine ring.
3. Determine the position of the phosphate group attachment. The phosphate group is attached to the 5' carbon of the pentose sugar, indicating that this is a 5'-monophosphate nucleotide.
4. Recognize the sugar in the nucleotide. The sugar is ribose, as indicated by the presence of hydroxyl groups (OH) on the 2' and 3' carbons, which is typical for ribonucleotides.
5. Combine the identified components to name the nucleotide. Since the base is cytosine, the sugar is ribose, and the phosphate is attached at the 5' position, the nucleotide is named cytidine 5'-monophosphate.
