Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.600\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) Cc1cc(S(=O)(=O)c2ccc([N+](=O)[O-])cn2)ccc1Br
(b) Cc1cccc(NC(=S)N2CCN(S(=O)(=O)c3ccccc3)CC2)c1
(c) CCc1cccc(NC(=O)CNC(=O)N2CC(=O)Nc3ccccc32)c1
(d) COc1ccc(OCc2nc(N)nc(Nc3cccc(C)c3C)n2)cc1
