Solution

The correct option is B $P - v, Q - i v, R - i, S - i i i$
(i) Hydrolase catalyse hydrolysis of ester, ether, peptide, glycosidic, C-C, halide or P-N bonds
(ii) Lyase catalyses removal of groups other hydrolysis.
(iii) Isomease catalyses inter-conversions of optical, geometric or positional isomers.
(iv) Ligase catalyses linking together of two compounds.
So, the correct option is option B.
