Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Sucrose is made up of two monosaccharides: glucose and fructose.These two monosaccharides are held together by a glycosidic linkage between C−1 of glucose and C−2 of fructose.
Since the reducing groups of glucose and fructose (i.e the free aldehyde/ketone groups) are involved in the glycosidic bond formation and are not available, sucrose is a non-reducing sugar.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
