The correct option is B $C u_{2} O$
Percentage of Cu $= \frac{Mass of copper}{Molecular mass of compound} \times 100$

Therefore using this formula,
the percentage of copper in $C u_{2} S, C u_{2} O, C u F e S_{2} a n d C u C O_{3} \cdot C u (O H)_{2}$ is 79.8, 88.8, 34.5 and 57.3 respectively.

The percentage of copper is maximum in $C u_{2} O$ .
