At 0.0°C, the densities of a cork and a liquid in which the cork floats are d1 and d2 respectively. The coefficient of expansion for the material of the cork and the liquid are γ and 100γ respectively. If the cork sinks when the temperature of the liquid is 't0°C', then the ratio d2/d1 is

A) 1 + 100γt / 1 + γt
B) 1 + γt / 1 + 100γt
C) 100 + γt / 1 + γt
D) 1 + γt / 100 + γt
