Refer to the given conversation among three friends.

All of our teeth have same basic structure of root, neck and crown and are made of a tough material called dentine.

If small intestine is removed from the body, digestion of food will take place but absorption of water from food will not occur.

The teeth at the back of jaw are premolars and molars. They both are found in milk teeth set as well as permanent teeth set.

People who do a lot of physical work, such as labourers, need to eat more of X. Y builds our muscles and helps us grow. Y is therefore known as body-building food. Z gives us more energy than X.
Read the given passage and select the correct option regarding the food nutrients X, Y and Z.

A Fruits have simple X and hence are digested quickly whereas wheat, corn, rice, potato, etc. have complex X and hence take more time to get digested.
B Y helps to repair damaged and hurt body parts.

D All of these
