Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.955% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc(-c2nc3c(c(=O)c4ccccc4n3C)c(=O)n2Cc2ccccc2)cc1
[b] Cc1ccc(-n2nc(C)c3c(C)c(CCC(=O)NCCCOC(C)C)c(C)nc32)cc1
[c] COc1cccc(OC(=O)N2CCOCC2)c1
[d] CC1CC(=O)N(c2ccc(NCc3ccc(Cl)cc3)c([N+](=O)[O-])c2)C1=O
Answer: d. CC1CC(=O)N(c2ccc(NCc3ccc(Cl)cc3)c([N+](=O)[O-])c2)C1=O
