Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -0.759\% 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 additional words.
Options:
(a) O=C(O)C(=O)O.O=C1CN(C(=O)CNCc2ccccc2Cl)c2ccccc2N1
(b) CCOc1ccccc1NC1=CC(=O)CC(c2ccccc2)C1
Answer: b. CCOc1ccccc1NC1=CC(=O)CC(c2ccccc2)C1
