For 'invert sugar', the correct statement(s) is/are) : [Given specific rotations of (+}·sucrose (+)-maltose, L-(-)-glucose and L-(+)-fructose in aqueous solution are +66°, +140°, -52° and +92° respectively.]

'invert sugar' is prepared by acid catalyzed hydrolysis of maltose

'invert sugar' is an equimolar mixture of D-(+)-glucose and D~(-).fructose

specific rotation of 'invert sugar' is -20°

on reaction with ${\mathrm{Br}}_2$ water, 'invert sugar' forms saccharic acid as one of the products
