Task: Answer the multiple choice question.
Query: Which compound exhibits a 27.058\% 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) Cc1ccc(C)c(NC(=O)CN(C)C(=O)c2ccc(S(=O)(=O)N(C)c3ccccc3)cc2)c1
(b) O=C(Nc1ccc2c(c1)CCC2)c1ccc(Br)s1
(c) O=C(/C=C/c1ccccc1[N+](=O)[O-])NCCCN1CCCC1=O
Answer: b. O=C(Nc1ccc2c(c1)CCC2)c1ccc(Br)s1
