Consider the mechanism

ClO^-(aq) +  HOCl(aq) + OH^-     K,fast
I^-(aq) + HOCl(aq) HOI(aq) +Cl^-(aq)     k1,slow
HOI(aq) + OH^-(aq) OI^-(aq) +H₂O(l)    k2,fast

What is the rate law?
a. k1K[CLO^-][I^-]
b. k1[I^-][HOCl]
c. k1K[CLO^-][I^-][OH^-]-1
d. k1K[CLO^-][I^-][OH^-]
e. k1k2K[CLO^-][I^-]

i know that to determine the rate law you have to find the rate for the slow step thus i got
rate= k1[I^-][HOCl]

however i know that HOCl can't be included in the rate law since it is an intermediate.
I'm kind of confused where to go from here, can anyone help me? thanks
