Solution

The correct option is D Thymine in place of uracil
The nitrogenous bases in RNA are adenine, guanine, cytosine and uracil. The nitrogenous bases are heterocyclic compounds with ring structure having atoms of two different elements.

In DNA, instead of uracil, thymine is present.

RNA is a polymer of nucleotides with 5' phosphoryl and 3' hydroxyl ends. 5' phosphoryl end refers to the terminal phosphate group on the 5' carbon. 3' hydroxyl end refers to the terminal hydroxyl group on the 3' carbon.
