A 2kg copper block is heated to \[500{}^\circ \text{ }C\] and then it is placed on a large block of ice at\[0{}^\circ C\]. If the specific heat capacity of copper is \[400\text{ }J/kg\,C{}^\circ \]and latent heat of fusion of water is \[3.5\times {{10}^{5}}J/kg\], the amount of ice that can melt is:

A) \[\frac{7}{8}\,kg\]

B)               \[\frac{8}{7}\,kg\]

C) \[\frac{5}{7}\,kg\]                     

D) \[\frac{7}{5}\,kg\]
