Task: Answer the multiple-choice question.
Question: Which drug exhibits a -7.535% 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 other words.
Options:
a.) O=C(Nc1ncc2c(n1)-c1ccccc1CC2)c1cccc(Cl)c1
