Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.441\% 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] CCOC(=O)c1ccc(NC(=O)CCNS(=O)(=O)c2cccs2)cc1
[b] CCOC(=O)/C(C#N)=C1/C=Cc2ccccc2N1CC
Answer: a. CCOC(=O)c1ccc(NC(=O)CCNS(=O)(=O)c2cccs2)cc1
