(D) The formula for volume expansion is $\Delta V = \gamma V_1 \Delta T$. Here,$\Delta V = V_2 - V_1 = 125 \, cm^3 - 100 \, cm^3 = 25 \, cm^3$. The initial volume $V_1 = 100 \, cm^3$. The change in temperature $\Delta T = 100 \, ^\circ C - 20 \, ^\circ C = 80 \, ^\circ C$. Substituting these values into the formula: $\gamma = \frac{\Delta V}{V_1 \Delta T} = \frac{25}{100 \times 80} = \frac{25}{8000} = 0.003125 \, ^\circ C^{-1}$. Rounding to the given options,the value is $0.0031 \, ^\circ C^{-1}$.
