Task: Answer the multiple choice question.
Query: Which drug exhibits a -15.124\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCCC(=O)Nc1cc(-c2nn(C)c(=O)c3ccccc23)ccc1N1CCOCC1
