Based on the behaviour of the metalloenzymes, consider the following statements
\[ \begin{array}{l} \text{(A) In the enzymes, the zinc activates } \mathrm{O_2}\text{, to form peroxide species.} \\ \text{(B) In the enzymes, the zinc activates } \mathrm{H_2O} \text{ and provides a zinc boud hydroxide.} \\ \text{(C) In the oxidases, the iron activates } \mathrm{O_2}\text{, to break the bonding between the two oxygens} \\ \text{(D) Zinc ion acts as a nucleophile and attacks at the peptide carbonyl} \end{array} \]
