Task: Answer the multiple choice question.
Question: Which compound has a 2.328\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(OC)c(CCNC(=O)CCC(=O)N2CCOc3ccc(C)cc32)c1
b: O=C(COc1ccccc1Br)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
c: CS(=O)Cc1cc(Oc2ccccc2)nc(-c2ccncc2)n1
Answer: b. O=C(COc1ccccc1Br)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
