Task: Answer the multiple choice question.
Query: Which drug exhibits a -19.500\% 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 other words.
Options:
a. CC1CCCN(c2nc3c(c(=O)[nH]c(=O)n3C)n2CCCc2ccccc2)C1
b. COc1ccc(/C=N\Nc2ncc(F)c(N3CCOCC3)n2)cc1OC
Answer: a. CC1CCCN(c2nc3c(c(=O)[nH]c(=O)n3C)n2CCCc2ccccc2)C1
