Given below are two statements .
Statement $\mathrm{I}$ : In ${\mathrm{CuSO}}_4·5{\mathrm{H}}_2\mathrm{O}, \mathrm{Cu}-\mathrm{O}$ bonds are present.

Statement $\mathrm{II}$ : In ${\mathrm{CuSO}}_4.5{\mathrm{H}}_2\mathrm{O}$, ligands coordinating with $\mathrm{Cu} \left(\mathrm{II}\right)$  ion are $\mathrm{O}$-and $\mathrm{S}$-based ligands.

In the light of the above statements, choose the correct answer from the options given below

In reference to water, choose the correct statement

(i) It gets oxidised to ${\mathrm{O}}_2$ during photosynthesis.

(ii) It gets reduced to ${\mathrm{H}}_2$ by highly electropositive metal.
