Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 14.342\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(C1CCCN1S(=O)(=O)c1ccc(Cl)c(Cl)c1)N1CCOCC1
(b) COc1ccc2[nH]c(=O)c(CN(C(=O)c3ccccn3)C3CCCCC3)cc2c1
(c) O=C(Nc1ccc(NC(=O)c2ccc([N+](=O)[O-])o2)cc1Cl)c1ccco1
(d) Cc1cc(=O)n2[nH]c(Nc3cccc(Cl)c3)nc2n1
Answer: c. O=C(Nc1ccc(NC(=O)c2ccc([N+](=O)[O-])o2)cc1Cl)c1ccco1
