‘D’ in the name of D-Glucose signifies
Direction of plane polarised light rotated by glucose
Position of the -OH group of right side of chiral carbon
Position of the H group of left side of chiral carbon
None of these
The D and L in the name of glucose refer to the direction of the -OH group of the chiral carbon which is farthest from the functional group. D-Glucose has -OH placed on the right side while L-Glucose has -OH placed on the left side. Hence, option 2 is the correct answer.
