Sucrose (cane sugar) is a disaccharide that means sucrose on hydrolysis produce two monosaccharide molecules.

Sucrose on hydrolysis produces equimolar mixture of D-glucose and D-fructose. These two monosaccharaides are held together by a glycosidic linkage between C1 of α-D-glucose and C2 of β-D-fructose Thus, option (iii) is correct.

Options (i), (ii) and (iv) are incorrect because sucrose on hydrolysis produces 1 molecule of D-glucose and 1 molecule of D-fructose.
