Which one is not gain by the hydrolysis of nucleoside?

(d) Pyrimidine is not gained by the hydrolysis of nucleosides. Nucleosides are composed of a purine or a pyrimidine base linked to a pentose sugar, which are cleaved from the backbone by hydrolysis. Thus, during hydrolysis of nucleosides, a purine and a pentose sugar are gained, but no pyrimidine is formed.
