2. Which one of the following Maxwell relations can be derived from one of the Gibbs equations, \( dU = TdS - PdV \)? (3%)
(A) \( \left( \frac{\partial T}{\partial P} \right)_S = \left( \frac{\partial V}{\partial S} \right)_P \)
(B) \( \left( \frac{\partial V}{\partial T} \right)_P = -\left( \frac{\partial S}{\partial P} \right)_T \)
(C) \( \left( \frac{\partial P}{\partial S} \right)_V = -\left( \frac{\partial T}{\partial V} \right)_S \)
(D) \( \left( \frac{\partial S}{\partial V} \right)_T = \left( \frac{\partial P}{\partial T} \right)_V \)
