Task: Answer the multiple choice question.
Query: Which drug exhibits a -7.613% 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) CCCn1c(SCc2cc(=O)[nH]c3ccccc23)nc2c1c(=O)n(C)c(=O)n2C
(b) COn1c(=O)c(-c2ccc(F)cc2)[n+]([O-])c2ccccc21
Answer: a. CCCn1c(SCc2cc(=O)[nH]c3ccccc23)nc2c1c(=O)n(C)c(=O)n2C
