Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.836% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COc1cc(CNc2nc(C)c([N+](=O)[O-])c(C)c2C#N)cc(OC)c1
[b] O=C(CN(CC1CCCO1)C(=O)CNS(=O)(=O)c1ccccc1)NCc1ccc(F)cc1
Answer: a. COc1cc(CNc2nc(C)c([N+](=O)[O-])c(C)c2C#N)cc(OC)c1
