The correct option is C Isomerases
Epimerases are isomerase enzymes that catalyze the inversion of stereochemistry in biological molecules.
Hydrolases are hydrolytic enzymes, biochemical catalysts that use water to cleave chemical bonds, usually dividing a large molecule into two smaller molecules.
Ligases are enzymes that can catalyze the joining of two large molecules by forming a new chemical bond, usually with accompanying hydrolysis of a small energy molecule like ATP.
Oxidoreductases are enzymes that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. This group of enzymes usually utilizes NADP or NAD+ as cofactors.
