Question Explanation: Verifying properties and linkage details of sucrose. Concept: Linkage and reducing nature of Sucrose. β Solution:

Assertion (A) is true; sucrose is a non-reducing disaccharide because its anomeric centers are locked. Reason (R) is false because sucrose involves a linkage between $C_{1}$ of $α$ -glucose and $C_{2}$ of $β$ fructose, not vice versa.

Assertion: Non-reducing (Correct).

Reason: C₁of β-glucose (Incorrect, should be α-glucose). Final Answer: Option (B)
