Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.288\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(=O)c1cccc(OCC(O)CN2CCN(S(=O)(=O)c3c(F)cccc3F)CC2)c1.O=C(O)C(=O)O
[b] O=C1NC2=C(C(=O)CCC2)C(c2ccc([N+](=O)[O-])cc2)N1
[c] CCOC(=O)CC(=O)CSc1nccc(-c2cccnc2)n1
Answer: b. O=C1NC2=C(C(=O)CCC2)C(c2ccc([N+](=O)[O-])cc2)N1
