Task: Answer the multiple-choice question.
Question: Which drug exhibits a -19.400% 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, b, c, or d without using any other words.
Options:
[a] Fc1ccc(C2=CC(c3ccc(Br)o3)n3ncnc3N2)cc1
