Task: Answer the multiple-choice question.
Query: Which drug has a 6.750\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) Cn1cc(-c2nnnn2-c2ccc(Cl)cc2)c(C(F)(F)F)n1
