Task: Answer the multiple-choice question.
Query: Which compound has a -9.440% 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(Nc1ccc(-c2ccccc2)cc1)C1=C(O)CCn2c1nc1ccccc12
(b) Cc1cc(C)c2c(NC(=O)C3CC3)nn(C)c2n1
(c) CCn1c(SCC(=O)Nc2cccc(C(C)=O)c2)nnc1C(C)C
(d) CC(C)CNC(=O)c1cccc(NC(=O)COc2cccc([N+](=O)[O-])c2)c1
Answer: a. O=C(Nc1ccc(-c2ccccc2)cc1)C1=C(O)CCn2c1nc1ccccc12
