Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.442\% 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=C(c1cn(-c2ccccc2)nc1-c1cccs1)N1CCN(c2ccc(F)cc2)CC1
