Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -19.598% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COc1ccc(-c2csc3ncn(-c4cccc(C)c4)c(=O)c23)cc1OC
[b] COc1cccc(C(=O)Nc2cccc(NC(=O)c3ccccc3Cl)c2)c1
Answer: a. COc1ccc(-c2csc3ncn(-c4cccc(C)c4)c(=O)c23)cc1OC
