Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.594\% 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) COc1ccc(-c2c(-c3ccccc3OC)sc3ccccc23)cc1C=O
(b) Cc1cc(C)n(CCC(=O)N/N=C/c2ccc(Cl)c([N+](=O)[O-])c2)n1
Answer: a. COc1ccc(-c2c(-c3ccccc3OC)sc3ccccc23)cc1C=O
