Task: Answer the multiple choice question.
Question: Which compound has a 0.207\% 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 other words.
Options:
a) Cc1csc(=O)n1CC(=O)OCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
b) CCOC(=O)c1ccc(N2NC(=O)/C(=C/c3ccc(OC(=O)c4ccco4)c(OC)c3)C2=O)cc1
c) O=C(COC(=O)Cc1ccccc1F)Nc1ccc(F)cc1F
d) CCCN(CC(=O)Nc1ccccc1C)C(=O)/C=C/c1ccc(S(=O)(=O)N2CCCCCC2)cc1
Answer: c. O=C(COC(=O)Cc1ccccc1F)Nc1ccc(F)cc1F
