answer is C)REACT WITH BOTH ACIDS AND BASES
ANSWER IS B) Phe-Ser-Ile-Lys
because Chymotrypsin preferentially cleaves peptide amide bonds where the carboxyl side of the amide bond (the P1 position) is a large hydrophobic amino acid (tyrosine, tryptophan, and phenylalanine).

Which sequence of amino acids, if any, would you predict to find in the interior of chymotrypsin (not the active site)? A. threonine, arginine, tyrosine B. glutamic acid, isoleucine, lysine C. valine, tryptophan, glycine D. None of the above. The answer is C, please explain why? Is it because those are hydrophobic amino acids?
