(C) is correct,bcos dis an exothermic reaction[i.e neutralisation]. High temp won't favout d reaction,but low temp,increase in reactant conc&surface area.There4 (D) is wrong!
The correct option is C
Because it is the Heat of neutralization and it is always exothermic
Meaning an increase in temperature would favour the reverse reaction
