Solution

The answer is C.2.

Here's the step-by-step explanation:

  1. Disaccharides are carbohydrates that consist of two monosaccharides (simple sugars) linked together.

  2. An anomeric carbon is the carbon derived from the carbonyl carbon (the carbon double-bonded to oxygen) of the open-chain form of the carbohydrate molecule.

  3. In the case of disaccharides like lactose, which are linked by β-glycosidic bonds, each of the two monosaccharides contributes one anomeric carbon to the bond.

  4. Therefore, there are 2 anomeric carbons in such disaccharides.
