Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.097% 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: O=[N+]([O-])c1cccc(-c2ccn[nH]2)c1
b: CCCCn1c(=O)[nH]c(=O)c2c1nc(-c1ccc(OC(F)F)c(OC)c1)n2C
Answer: b. CCCCn1c(=O)[nH]c(=O)c2c1nc(-c1ccc(OC(F)F)c(OC)c1)n2C
