Dairy foods contain a sugar called lactose that is broken down in the digestive system. Some people get an upset stomach when they eat dairy foods, such as milk and ice cream. These people lack an enzyme called lactase that is involved in the digestion of lactose. Lactase supplements have been developed that make it possible for these people to eat dairy foods. What can be inferred about the action of the lactase supplement?

It speeds the breakdown of all types of food molecules, including dairy.

It protects the stomach from acid, reducing stomachache caused by lactose.

It lowers the activation energy for the reaction that breaks down lactose.

It increases the amount of stomach acid to enhance lactose digestion.
