Task: Answer the multiple choice question.
Query: Which compound has a 18.327% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(O)Cn1c(=O)c(-c2ccccc2)nc2ccccc21
(b) CC(=O)Nc1ccc(S(=O)(=O)Nc2nc3ccccc3nc2N2CCCCCC2)cc1
(c) Cc1cc(C)c2nc(N3C(=O)C(O)=C(C(=O)c4ccco4)C3c3ccc(O)cc3)sc2c1
(d) CCC(=O)OCC(=O)Nc1cc(C)c(C)cc1[N+](=O)[O-]
Answer: c. Cc1cc(C)c2nc(N3C(=O)C(O)=C(C(=O)c4ccco4)C3c3ccc(O)cc3)sc2c1
