Task: Answer the multiple-choice question.
Query: Which compound exhibits a 1.165\% 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 other words.
Options:
a.) O=C(Nc1cc([N+](=O)[O-])ccc1Cl)C(Sc1ccccc1)c1ccccc1
b.) COc1ccc(N2CC(C(=O)N3CCC4(CC3)CC(=O)c3ccccc3O4)CC2=O)cc1
Answer: a. O=C(Nc1cc([N+](=O)[O-])ccc1Cl)C(Sc1ccccc1)c1ccccc1
