Which of the following can help someone who is lactose intolerant enjoy dairy products?

Eliminate incorrect options: Avoiding all carbohydrates is not relevant to lactose intolerance, as lactose is a specific carbohydrate, not all carbohydrates. Increasing vitamin D intake does not address lactose digestion, and drinking more water does not aid in breaking down lactose.

Explain the mechanism: Lactase enzyme supplements work by hydrolyzing lactose into its simpler components, glucose and galactose, which can be absorbed by the small intestine. The chemical reaction can be represented as: ${\mathrm{Lactase}}_{\mathrm{enzyme}}:{\mathrm{Lactose}}_{\mathrm{(C₁₂H₂₂O₁₁)}}\to {\mathrm{Glucose}}_{\mathrm{(C₆H₁₂O₆)}}+{\mathrm{Galactose}}_{\mathrm{(C₆H₁₂O₆)}}$
