Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -12.798\% 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.) COc1ccc(NC(=O)CN(C)C(=O)Cn2cnc3c2c(=O)n(C)c(=O)n3C)cc1
b.) COCc1cc(C)c(C#N)c(=S)[nH]1
Answer: b. COCc1cc(C)c(C#N)c(=S)[nH]1
