Solution
The correct option is A Sucrose
When sucrose (C12H22O11) is boiled with dilute HCl or H2SO4 in an alcoholic solution, glucose and fructose are obtained in equal amounts. This is one of the methods used for preparation of glucose and called hydrolysis of sucrose. On hydrolysis, lactose gives galactose and glucose. Maltose on hydrolysis gives two molecules of glucose only. Starch being a polysaccharide, give many monomers of glucose.
Hence, (a) is correct.
