Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Reducing sugar gives a red precipitate with Fehling's solution and show mutarotation.
Reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. All monosaccharides are reducing sugars, along with some disaccharides, oligosaccharides, and polysaccharides.
During mutarotation, one pure anomer is converted into a mixture of two anomers
Mutarotation is the change in the optical rotation because of the change in the equilibrium between two anomers when the corresponding stereocenters interconvert. Cyclic sugars show mutarotation as and anomeric forms interconvert.

Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Hence, the correct option is $A$
