Task: Answer the multiple choice question.
Query: Which compound exhibits a 19.370\% 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 additional words.
Options:
a) O=C1OCc2cc(NC(=O)C34CC5CC(CC(C5)C3)C4)ccc21
b) CCOc1ccc(CNC(=O)CCCOc2cc(=O)n(C)c3ccccc23)cc1
Answer: a. O=C1OCc2cc(NC(=O)C34CC5CC(CC(C5)C3)C4)ccc21
