Which of the following nitrogen base is not present in the RNA?

Introduction - RNA & Nitrogen Base

Ribonucleic corrosive (RNA) is a polymeric atom fundamental in different organic parts in coding, translating, direction, and articulation of qualities. RNA and DNA are nucleic acids, and, alongside lipids, proteins and starches, constitute the four noteworthy macromolecules fundamental for every single known type of life. Like DNA, RNA is collected as a chain of nucleotides, however dissimilar to DNA it is all the more frequently found in nature as a solitary strand collapsed onto itself, as opposed to a combined twofold strand. 

Nitrogenous base: An atom that contains nitrogen and has the substance properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one special case: adenine (A), guanine (G), uracil (U), and cytosine (C).

Answer: Right Answer is Option (D)
