which one of the following sets of monosaccharides forms

Which one of the following sets of monosaccharides forms sucrose?

A. $$\alpha {\text{ - }}D{\text{ - }}$$ Galactopyranose and $$\alpha {\text{ - }}D{\text{ - }}$$ glucopyranose

B. $$\alpha {\text{ - }}D{\text{ - }}$$ Glucopyranose and $$\beta {\text{ - }}D{\text{ - }}$$ fructofuranose

C. $$\beta {\text{ - }}D{\text{ - }}$$ Glucopyranose and $$\alpha {\text{ - }}D{\text{ - }}$$ fructofuranose

D. $$\alpha {\text{ - }}D{\text{ - }}$$ Glucopyranose and $$\beta {\text{ - }}D{\text{ - }}$$ fructopyranose

Answer : $$\alpha {\text{ - }}D{\text{ - }}$$ Glucopyranose and $$\beta {\text{ - }}D{\text{ - }}$$ fructofuranose

Solution :
Sucrose is formed by the condensation of $$\alpha {\text{ - }}D{\text{ - }}$$ glucopyranose and $$\beta {\text{ - }}D{\text{ - }}$$ fructofuranose.
