Task: Answer the multiple choice question.
Query: Which compound exhibits a -34.954% 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=C1c2ccc([N+](=O)[O-])cc2NC(c2ccco2)N1/N=C/c1ccco1
[b] O=C(COc1ccc(Br)cc1)Nc1cc(S(=O)(=O)N2CCCCC2)ccc1N1CCCCC1
[c] O=[N+]([O-])c1ccccc1S(=O)(=O)Nc1ccc(-c2ccc(N3CCCC3)nn2)cc1
[d] CSCC[C@H](NC(=O)C1CCN(S(=O)(=O)c2ccc(C)cc2)CC1)C(=O)NC1CCS(=O)(=O)C1
Answer: a. O=C1c2ccc([N+](=O)[O-])cc2NC(c2ccco2)N1/N=C/c1ccco1
