The correct option is D A-5; B-3, 4; C-1,3; D-2,3
When glucose is treated with methanol in presence of HCl gas, glucosides are obtained.
Hydrolysis of sucrose gives glucose.
Fructose, on treatment with base, gives mannose and glucose. This is a rearrangement reaction.
The hydrolysis of lactose gives galactose and glucose.
