Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.314\% 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) CCOc1c(Nc2cccc(Cl)c2)c(=O)c1=O
(b) Cc1ccc(NC(=O)CSC2=C(C#N)C(c3ccc4c(c3)OCO4)C3=C(CCCC3=O)N2)c(C)c1
Answer: a. CCOc1c(Nc2cccc(Cl)c2)c(=O)c1=O
