Hi,
Hope you are doing well.
The given reaction has a negative enthalpy of reaction. Hence the given reaction is an exothermic reaction.
We know that the exothermic reactions favour low temperature.
Now, checking the total number of moles of gaseous molecules on both sides of the reaction, no.of moles of reactants is greater than that of product. Hence the given reaction prefers high pressure.
So the correct option is OPTION B. Low temperature, high pressure.
