\nDigestion breaks down complex molecules into simpler units that can be absorbed by the body.
\n– Proteins are polymers of amino acids, and digestion breaks them down into individual amino acids. (A -> 4)
\n– Carbohydrates (like starch, disaccharides) are broken down into monosaccharides (simple sugars like glucose, fructose, galactose). (B -> 3)
\n– Nucleic acids (DNA, RNA) are broken down into nucleotides, and further breakdown yields nitrogenous bases, pentose sugars, and phosphate groups. Option 1 lists nitrogenous bases and pentose sugars, which are components resulting from nucleic acid digestion. (C -> 1)
\n– Lipids (fats and oils) are broken down into fatty acids and glycerol. (D -> 2)
