Solution

The symptoms described in the question are indicative of lactose intolerance. Lactose intolerance is a common digestive disorder where the body is unable to fully digest lactose, a sugar found in milk and dairy products. This is caused by a deficiency in an enzyme called lactase, which is produced in the small intestine. Lactase is needed to break down lactose into glucose and galactose, which can then be absorbed into the bloodstream and used for energy. Without enough lactase, lactose stays in the digestive system where it ferments, causing the symptoms mentioned in the question. Therefore, the correct answer is b. Lactase.
