Task: Answer the multiple choice question.
Query: Which compound has a 18.033\% 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(CNCc1ccccc1Cl)Nc1ccccc1N1CCCCC1.O=C(O)C(=O)O
b: CCCCOC(=O)c1ccc(NC(=O)C2CCCO2)cc1
Answer: a. O=C(CNCc1ccccc1Cl)Nc1ccccc1N1CCCCC1.O=C(O)C(=O)O
