Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.434\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COC(=O)Cn1c(N)[n+](Cc2ccccc2)c2ccccc21.[Br-]
b: O=C(Oc1c(-c2ccccc2)c(=O)n2c3c(cccc13)CC2)c1ccc(Cl)cc1
c: CC(=O)c1ccc(C(=O)N2CCCC(C(=O)c3ccc(Cl)cc3)C2)s1
Answer: b. O=C(Oc1c(-c2ccccc2)c(=O)n2c3c(cccc13)CC2)c1ccc(Cl)cc1
