Given below are two statements : one is labelled as Assertion (A) and other is labelled as Reason (R). 

Assertion (A) : Sucrose is a disaccharide and a non-reducing sugar. 

Reason (R) : Sucrose involves glycosidic linkage between C₁ of β-glucose and C₂ of α-fructose. 

Choose the most appropriate answer from the options given below :

(1) Both (A) and (R) are true but (R) is not the true explanation of (A) 

(2) (A) is false but (R) is true.
