Task: Answer the multiple-choice question.
Query: Which compound exhibits a 19.403\% 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.) O=C(Nc1cccc(Cl)c1Cl)C1CCN(c2ncccn2)CC1
