Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.633% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc(N=Nc2c(O)[nH]c(=S)[nH]c2=O)cc1
