Task: Answer the multiple choice question.
Question: Which compound has a -7.257\% 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 CCc1ccc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NCC2CCCO2)c2ccccc2)cc1
b CC(=O)N(c1nnc(-c2cccc(C)c2)s1)C1CCCC1
c O=[N+]([O-])c1ccc(-c2nnc(-c3ccccc3)c(N3CCOCC3)n2)cc1
d O=C(NCc1cccc(F)c1F)C1CCC(=O)N(C2CCCCCC2)C1
Answer: c. O=[N+]([O-])c1ccc(-c2nnc(-c3ccccc3)c(N3CCOCC3)n2)cc1
