Task: Answer the multiple-choice question.
Query: Which compound has a -9.634% 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(Cc1ccc([N+](=O)[O-])cc1)N/N=C/c1cccnc1
b: COc1cccc(NC(=O)c2ccc3nc(C)sc3c2)c1
c: Cc1cc(C)nc(NC(=O)c2cccc(Br)c2)n1
d: COc1cccc(C(=O)NC2CC3CCC(C2)N3Cc2ccccc2)c1
Answer: a. O=C(Cc1ccc([N+](=O)[O-])cc1)N/N=C/c1cccnc1
