Task: Answer the multiple-choice question.
Query: Which compound has a 18.806\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(NCc1cccc(F)c1)C1CCN(C(=O)c2sccc2-n2cccc2)CC1
(b) COc1cccc2sc(Nc3nc(-c4ccccn4)cs3)nc12
(c) Cn1ccs/c1=N\S(=O)(=O)c1ccc(Br)cc1
Answer: c. Cn1ccs/c1=N\S(=O)(=O)c1ccc(Br)cc1
