Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.958% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCC(CC)NCc1ccc(OC)cc1OC
b: COc1cc(C2Nc3c(F)cccc3C3C=CCC32)cc(Br)c1OC
c: CCN(CC)c1ccc(NC(=O)c2cccnc2)cc1
d: O=C(CN1CCN(Cc2ccccc2)CC1)Nc1ccc(Cl)cn1
Answer: b. COc1cc(C2Nc3c(F)cccc3C3C=CCC32)cc(Br)c1OC
