A: Entropy of a perfect crystalline solid at absolute zero approaches zero.
B: For spontaneity of a reaction, \(T\Delta S > \Delta H\).
Among the two statements given above, identify the correct answer from the options given below.

Statement A is based on the third law of thermodynamics, which states that the entropy of a perfectly crystalline solid approaches zero as the temperature approaches absolute zero. Thus, Statement A is true.

For a reaction to be spontaneous at constant temperature and pressure, the change in Gibbs free energy (\(\Delta G\)) must be negative (\(\Delta G < 0\)).

From the Gibbs-Helmholtz equation:
\(\Delta G = \Delta H - T\Delta S\)

For spontaneity, \(\Delta G < 0\)
\(\Rightarrow \Delta H - T\Delta S < 0\)
\(\Rightarrow T\Delta S > \Delta H\)

Thus, Statement B is also true.

Both Statement A and Statement B are true.

Answer: Both '\(A\)' and '\(B\)' are true
