Mutarotation and its meaning:
Mutarotation is a chemical reaction that occurs when a cyclic molecule in solution changes its optical rotation due to the equilibrium between two anomers.
Explanation of options:
a) Racemization: This refers to the conversion of an optically active compound into a racemic mixture of equal amounts of its enantiomers. This process is not related to mutarotation.
b) Conformational inversion: This refers to the change in orientation of substituents in a molecule while maintaining the same connectivity. This process is not related to mutarotation.
c) Optical resolution: This refers to the process of separating a racemic mixture into its individual enantiomers. This process is not related to mutarotation.
d) Diastereomerization: This refers to the conversion of one diastereomer into another diastereomer. In the case of mutarotation, the cyclic molecule in solution can exist as two anomers (diastereomers) in equilibrium. As the equilibrium shifts, the optical rotation of the solution changes. Therefore, the correct answer is option D.
Conclusion:
Mutarotation involves the conversion of a cyclic molecule in solution between two diastereomers, resulting in a change in optical rotation. Therefore, the correct answer is diastereomerization.

Mutarotation involves diastereomerisation...
Mutarotation is the change in the optical rotation because of the change in the equilibrium between two anomers,when the corresponding stereocenters interconvert.
Cyclic sugar shows mutarotation as alpha and beta anomeric form interconvert.
The optical rotation of the solution depends on the optical rotation of each anomer and their ratio in the solution. The alpha & beta anomers are diastereomers of each other and usually have different specific rotations...
So, the correct answer is option (D)...
