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 \(C_{1}\) of \(\beta\)-glucose and \(C_{2}\) of \(\alpha\)-fructose. Choose the most appropriate answer from the options given below :

1. A Both \((A)\) and \((R)\) are true but \((R)\) is not the true explanation of \((A)\)
2. B \((A)\) is false but \((R)\) is true.
3. C \((A)\) is true but \((R)\) is false
4. D Both \((A)\) and \((R)\) are true and \((R)\) is the true explanation of \((A)\)
