At 298 K, the enthalpy change for a given reaction K is $-x$ cal/mol. If the reaction occurs spontaneously at 298 K, the entropy change at that temperature

Question

(a) can be negative, but numerically larger than $\frac{x}{298} cal K^{-1}$
(b) can be negative, but numerically smaller than $\frac{x}{298} cal K^{-1}$
(c) cannot be negative
(d) cannot be positive
