Solution

The correct option is B Uracil
One of the most important differences between DNA and RNA apart from the sugar molecule is the nitrogenous base Uracil, which is seen only in RNA. Instead of Uracil, DNA has Thymine, while the other three nitrogenous bases (Adenine, Guanine, Cytosine) are the same in both RNA and DNA.
