Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -7.918\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COC(=O)c1nc2n(n1)C(c1cccc(Cl)c1)C1=C(CC(C)(C)CC1=O)N2
b: O=C1NC(c2ccc(Br)cc2)Nc2sc3c(c21)CCC3
c: CCOC(=O)c1ccc(S(=O)(=O)NC2CCC(C)CC2)cc1
Answer: b. O=C1NC(c2ccc(Br)cc2)Nc2sc3c(c21)CCC3
