The correct answer is:
A nucleoside tetraphosphate yields upon complete hydrolysis one nucleobase, one sugar, and four phosphates.
A tetranucleotide yields four bases, four sugars, and at least three phosphates.
Nucleosides are glycosylamines that can can be defined as a nucleotides without a phosphate group. So, nucleoside is composed of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) without the phosphate group. On the other hand, nucleotide is composed of a nitrogenous base, a sugar and one to three phosphate groups.
