Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 3.845\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1cc(C(=O)NC(=S)NCc2ccco2)cc(OC)c1OC
(b) CC(NC(=O)Cc1ccsc1)c1ccc(S(N)(=O)=O)cc1
(c) CC(=O)N1N=C(c2cccc([N+](=O)[O-])c2)OC1c1ccc(Cl)cc1Cl
Answer: a. COc1cc(C(=O)NC(=S)NCc2ccco2)cc(OC)c1OC
