If someone is lactose intolerant, they lack the enzyme ____
A
lipase
B
lactose
C
lactase
D
milk
Explanation: 

Detailed explanation-1: -Lactose intolerance occurs when your small intestine doesn’t produce enough of an enzyme (lactase) to digest milk sugar (lactose). Normally, lactase turns milk sugar into two simple sugars-glucose and galactose-which are absorbed into the bloodstream through the intestinal lining.

Detailed explanation-2: -Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase. Lactase breaks down the lactose in food so your body can absorb it. People who are lactose intolerant have unpleasant symptoms after eating or drinking milk or milk products.

Detailed explanation-3: -Lactose is a type of sugar found in milk and other dairy products. An enzyme called lactase is needed by the body to digest lactose. Lactose intolerance develops when the small intestine does not make enough of this enzyme.

Detailed explanation-4: -In lactose intolerance, the body doesn’t make enough lactase to break down lactose. Instead, undigested lactose sits in the gut and gets broken down by bacteria, causing gas, bloating, stomach cramps, and diarrhea. Lactose intolerance is fairly common.
