Explanation:

When food is ingested,the action of several enzymes and gastric juices by saliva,stomach and other accessory digestive organs break them into the simpler biomolecules like fatty acids,small proteins(peptides),glucose or simple sugar and amino acids. No matter how heavy starch,carbohydrates based or protein ,lipids and fats based food you eat,the end product will always be this simple biomolecules and this is what is called digested food or nutrients.

• Our blood have 55% liquid component called blood plasma. This glucose, fatty acids,amino acids are absorbed primarily by stomach walls and then by small intestine lining and this goes into blood(plasma) and is dissolvable in plasma. This is then carried into the other parts of organs/tissues/cells.

Hence option 2nd is correct.
