If this is for a Basic Nutrition chapter assignment, the choices are as follows:
a. vitamins
b. minerals
c. water
d. carbohydrates
The answer that you are looking for is carbohydrates. Proteins, lipids, and carbohydrates must be digested before they are absorbed.
Carbohydrates by salivary amylase in mouth
Carbohydrates are broken down by amylase in the mouth.
the organ that absorbs nutrients during digestion is the small intestine. the walls of the small intestines will absorb digested nutrients into the blood stream
Digestion of food starts from Saliva
protein
Yes- to be more specific they are "emulsified" by bile, before it is absorbed.

Vitamins are not be digested before absorption. The same is true for the minerals. They need not be digested before absorption.
Glucose is a monosaccharide, so it does not need to be broken down any further. It can be absorbed without any changes.
The nutrients that do not need to be digested they have to be smaller than the cells of the small intestine. Some of these are sugars and amino acids.
No. It is absorbed.
Water is water. It is already in the right form to be absorbed, no breakup needed.
When nutrients are digested they are then absorbed into the blood stream. The cardiovascular system then distributes those nutrients to the different areas of the body that are in need of them.
Because a steak does your body no good directly. However by breaking down (digesting) the food to the basic components like amino acids, then your body absorbs the essential nutrients and leaves the rest in the digestive tract.

That's correct.
No they use osmosis to absorb digested nutrients and flagella to move food and particles around within it
