Consider the following statements: Statement-I: All monosaccharides are reducing sugars. Statement-II: Sucrose can reduce ammoniacal silver nitrate solution. Choose the correct answer from the options given below.

Step-by-step solution

Statement-I is correct because all monosaccharides contain a free aldehyde or ketonic group in their open-chain structure, which allows them to act as reducing agents. Thus, all monosaccharides are reducing sugars. Statement-II is incorrect because sucrose is a non-reducing sugar. In sucrose, the two monosaccharide units (glucose and fructose) are held together by a glycosidic linkage between C1 of -D-glucose and C2 of -D-fructose. Since the reducing groups of both glucose and fructose are involved in glycosidic bo
