Solution

The correct option is C $C_{1}$
Anomeric carbon is the carbon which has four different group at first carbon. All the four groups attached to the first carbon are attached to four different valence shell of carbon. First carbon of the glucose is anomeric as it is attached to four different group OH, C, H and O.
So, the correct answer is option A.
