The correct answer is: D-glucose + D-fructose
Invert sugar is a mixture of D-glucose and D-fructose.
Solution of sucrose is dextrorotatory. When sucrose is hydrolysed it forms equimolar quantity of D-glucose and D-fructose. The solution of formed products is found to be laevorotatory. This change in optical properties of sucrose is called inversion of cane sugar. The equimolar product formed, i.e D-glucose and D-fructose is called invert sugar.
