Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.985\% 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 additional words.
Options:
a) Cc1ccc(C2=CC(c3ccc(C)cc3)n3ncnc3N2)cc1
b) CCC(C)C(NC(=O)CCC(=O)OCC(=O)[C@@]1(O)CCC2[C@@H]3CCC4=CC(=O)C=C[C@]4(C)C3[C@@H](O)C[C@@]21C)C(=O)O
c) Cc1ccccc1NC(=O)Cc1cn(C)c2ccccc12
d) CC(=O)c1nn(-c2cccc(Br)c2)cc1C(=O)c1ccc(Cl)cc1
