Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.469\% 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)c1sc(NC(=O)CSc2n[nH]c(-c3ccc(Cl)cc3Cl)n2)c(C#N)c1C
(b) COc1ccc(N(CC(=O)Nc2ccc(OC)c(OC)c2)S(=O)(=O)c2ccccc2)cc1Cl
Answer: a. CCOC(=O)c1sc(NC(=O)CSc2n[nH]c(-c3ccc(Cl)cc3Cl)n2)c(C#N)c1C
