#2 - adding a catalyst
#3 - doubling the concentration of reactant C

a. only one of these (only #1 or only #2 or only #3)
b. #1 and #2 only
c. #1 and #3 only
d. #2 and #3 only
e. all three will result in an increase in the rate constant for the reaction.

The rate CONSTANT changes with T but it does not change with the addition of a catalyst or changing concn. Adding a catalyst WILL change the rate (but not the constant) and changing the concn of C WILL change the rate but not the constant.
