The answer is A. cannot break down the lactose found in milk. Lactose is
a disaccharide composed of glucose and galactose. It is found in milk
in 2-8%. Lactose-intolerant people cannot break down the lactose into
glucose and galactose. Undigested lactose in the gastrointestinal tract
can cause belly pain, bloating, and gas.
