A carbot freezer takes heat from water at `0^(@)C` inside it and rejects it to the room at a temperature of `27^(@)C`. The latent heat of ice is `336xx10^(3)Jkg^(-1)`. If 5kg of water at `0^(@)C` is converted into ice at `0^(@)C` by the freezer, then the energy consumed by the freezer is close to :

A

`1.67 xx 10^(5) J`

B

`1.68 xx 10^(6) J`

C

`1.71 xx 10^(7) J`

D

`1.51 xx 10^(5) J`
