Rate law of chemical reaction

The rate of the following reaction in aqueous solution is monitored by measuring the rate of formation of (I3^-). The data obtained is listed in the table.
(S2O8^2-) + (3I^-) ----> (2SO4^2-) + (I3^-)
Experiment ([S2O8]^2-), M ([I]^-),M Initial rate, M s^1-
1 0.038 0.060 1.4 x 10^-5
2 0.076 0.060 2.8 x 10^-5
3 0.076 0.120 5.6 x 10^-5
1.) Determine the order of the reaction with respect to (S2O8^2-), with respect to (I^-), and the overall order.(Choose the correct letter choice.)

A.)Order with respect to (S2O8^2-)
a.zeroth
b.first
c.second
d.third
e.fourth

B.)Order with respect to (I^-)
a.zeroth
b.first
c.second
d.third
e.fourth

C.)Order of the reaction
