Solution
The correct option is C Low temperature and high pressure
As the ΔH is negative, reaction is exothermic so there should be low temperature for reaction to proceed. From left to right as no. of moles are decresing so according to Le Chatelier's principle at high pressure reaction will proceed in forward direction.
Hence, for reaction to proceed in forward direction there should be low temperature and high pressure.
