Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.648\% 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: CN1CCN(CC(O)Cn2c3ccccc3c3ccccc32)CC1.O=C(O)C(=O)O
b: COc1cc(C2NC(=O)NC(C)=C2C(=O)OCC2CCCCC2)ccc1O
Answer: a. CN1CCN(CC(O)Cn2c3ccccc3c3ccccc32)CC1.O=C(O)C(=O)O
