Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.633\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) O=c1oc2ccccc2cc1-c1csc(Cc2nc(-c3ccc(Cl)cc3)cs2)n1
