Task: Answer the multiple-choice question.
Question: Which drug exhibits a -8.333% 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 other words.
Options:
(a) CC(C)=CC(=O)NCCc1ccccc1
(b) O=C(CN1C(=O)C2CCCCC2C1=O)OCC(=O)c1ccc(Cl)s1
Answer: b. O=C(CN1C(=O)C2CCCCC2C1=O)OCC(=O)c1ccc(Cl)s1
