Explanation

Dietary fats are digested by lipases — chiefly pancreatic lipase in the small intestine — which split triglycerides into fatty acids and glycerol. Trypsin and chymotrypsin are proteases acting on proteins (A is wrong); starch is digested by amylases (B is wrong); nucleic acids are digested by nucleases, not amylases (D is wrong). Hence only C is correct.
