The building blocks of di-saccharides (sucrose) and poly-saccharides are
-
oligo-saccharides
-
Mono-saccharides
-
Poly-saccharides
-

B
Correct answer
Explanation
Mono-saccharides are the most basic units of biologically important carbohydrates. They are the simplest form of sugar and are usually colorless, water-soluble, crystalline solids. Some mono-saccharides have a sweet taste. Mono-saccharides are the building blocks of di-saccharides such as sucrose and poly-saccharides.
