Evaluate the conditions necessary for mutarotation to occur in a solution.

• A. Mutarotation occurs in the presence of free anomeric carbons in solution, allowing interconversion between anomers.
• B. Mutarotation occurs in the absence of free anomeric carbons, allowing interconversion between anomers.
• C. Mutarotation occurs in the presence of stable covalent bonds, allowing interconversion between anomers.
• D. Mutarotation occurs in the presence of a catalyst, allowing interconversion between anomers.

Answer: (A)
