Thank you, But I have to have 100% correct answers. Haha

What an untidy and ambiguous question. Which is not your fault. It depends on how much you increase the temp of the reactants or how much you decrease the pH of the solution. Bronze is correct on that score.

muzzack · Answer

A,C and D would stop the enzyme from doing its work(speeding up the reaction).
