The Correct Option is
Solution and Explanation
Concept:
Sucrose is a non-reducing disaccharide composed of glucose and fructose.
Step 1: Check each statement.
• (i) True $\rightarrow$ sucrose is a disaccharide
• (ii) False $\rightarrow$ sucrose is non-reducing
• (iii) False $\rightarrow$ sucrose is dextrorotatory (not laevorotatory)
• (iv) True $\rightarrow$ gives equimolar glucose and fructose on hydrolysis
• (v) True $\rightarrow$ linked by glycosidic bond
Step 2: Select correct statements.
\[ (i), (iv), (v) \]
