Answer :

I am pretty sure that the statement which is about reaction rate is accurate is C. All chemical reactions occur at different rates. I bet you will agree with me if I provide m y answer with some examples : cooking food is a chemical reaction indeed;  which means that some food can be made faster or slower than other ones.
