Task: Answer the multiple choice question.
Question: Which drug exhibits a -16.977% 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 additional words.
Options:
a: CC1(C)CC(=O)C(C2(O)C(=O)N(Cc3ccccc3)c3ccccc32)CO1
b: CCOC(=O)c1c(-n2cccc2)sc2c1CCCC2=O
Answer: b. CCOC(=O)c1c(-n2cccc2)sc2c1CCCC2=O
