Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.325\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COC(=O)c1c(NC(=O)c2cccc(S(=O)(=O)N3CCN(C)CC3)c2)sc(C)c1C
b: Cc1ccc(C2=Nc3ccc(Br)cc3C(c3ccncc3)=NN2)cc1
Answer: a. COC(=O)c1c(NC(=O)c2cccc(S(=O)(=O)N3CCN(C)CC3)c2)sc(C)c1C
