Options
A α-D-glucopyranose
Correct Answer
B methyl β-D-glucopyranoside
C sucrose
D methyl α-D-ribofuranoside
Correct Answer

Option A is the correct answer.

Detailed Explanation

α-D-glucopyranose is a reducing sugar (free hemiacetal OH) and gives a positive Tollens' test. Glycosides (methyl glucopyranoside, methyl ribofuranoside) and sucrose are non-reducing sugars and do not reduce Tollens' reagent.
