Three structures A. (A) is between C1 and C4, (B) and (C) are between C1 and C6

B. (A) and (B) are between C1 and C4, (C) is between C1 and C6

C. (A) and (C) are between C1 and C4, (B) is between C1 and C6

D. (A) and (C) are between C1 and C6, (B) is between C1 and C4

The linkages between C1 and C4 of glucose are represented in the picture as ‘A’ and ‘C’ and ‘B’ is the linkage between C1 and C6 of the glucose units. Also, upon looking at the structures it is clear that option (iii) is correct.

Option (ii) is incorrect because ‘B’ is the linkage between C1 and C6 of the glucose units.

Option (i) is incorrect because ‘C’ is the linkage between C1 and C4 of the glucose units.

Option (iv) is incorrect because ‘A’ is the linkage between C1 and C4 of the glucose units.
