For the reaction to be feasible the \Delta G should be negative
\Delta G = \Delta H - T\Delta S

According to question,
\Delta S = positive unit
\Delta H = negative (as heat is evolved in the reaction)
Overall the \Delta G is negative.

Therefore the reaction is possible at any temperature. So, the correct option is (iv)
