Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.421% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(Cc1cccs1)Nc1cccc(-c2nc3cc4ccccc4cc3[nH]2)c1
