Identify $[\mathrm{X}]$, the final product formed when 2 moles of Ethanal undergoes the following series of reactions with reagents [(i) to (iv)]
Two statements, one Assertion (A) and the other Reason (R) are given. Choose the correct option.
Assertion: Maltose, a disaccharide, is a reducing sugar and is obtained by the partial hydrolysis of starch in presence of the enzyme diastase.
Reason: Hydrolysis of one mole of Maltose gives one mole each of $\alpha-D-$ Glucose and $\beta-D-$ Fructose.
