Task: Answer the multiple-choice question.
Query: Which compound has a 19.572% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)C(NC(=O)c1ccccc1)=C(Cl)Cl
[b] Nc1ccn(CC(=O)N2CCN(c3ccccn3)CC2)c(=O)n1
Answer: a. O=C(O)C(NC(=O)c1ccccc1)=C(Cl)Cl
