Answer 1

I think the answer is Lactose + glucose → galactose

Answer 2

The answer is Galactose + Glucose= lactose. In order for the lactose to be absorbed in the body, there is a need of splitting it into galactose and glucose. Lactose is a type of sugar that is found in milk and other dairy products. The other choices are wrong because they cannot form the disaccharides given.
