Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.267\% 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] COC(=O)c1cscc1S(=O)(=O)Cc1ccccc1
[b] CCOC(=O)C1=C(C)NC(=O)NC1c1ccc(OCC(N)=O)cc1
[c] COc1ccc(-c2csc3ncnc(N4CCN(S(=O)(=O)c5cccc(Br)c5)CC4)c23)cc1
Answer: b. CCOC(=O)C1=C(C)NC(=O)NC1c1ccc(OCC(N)=O)cc1
