Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.194\% 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(Nc1cccc(-c2nc3cc(Cl)ccc3o2)c1)C1CCCO1
b: CN1CCc2c(OCC(=O)N3CCCc4ccccc43)cccc2C1=O
Answer: a. O=C(Nc1cccc(-c2nc3cc(Cl)ccc3o2)c1)C1CCCO1
