Task: Answer the multiple choice question.
Question: Which drug exhibits a -17.814% 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 additional words.
Options:
[a] COc1ccc(-c2nnc(SCc3nc4ccccc4c(=O)[nH]3)o2)cc1
[b] Cc1ccc(-c2nnn(CC(=O)NCCc3ccc4c(c3)OCO4)n2)cc1
Answer: a. COc1ccc(-c2nnc(SCc3nc4ccccc4c(=O)[nH]3)o2)cc1
