A new temperature scale uses X as a unit of temperature, where the numerical value of the temperature `t_(x)` in this scale is related to the absolute temperature T by `t_(x) = 3T + 300`. If the specific heat of a material using this unit is `1400 J kg_(1)X_(1)` its specific heat in the S.I. system of units is- c
A. 4200 J `Kg^(-1)K^(-1)`
B. 1400 J `Kg^(-1)K^(-1)`
C. 466.7 J `Kg^(-1)K^(-1)`
D. impossible to determine from the information provided
