Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.212\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOc1ccc(-c2nc3c(s2)CCc2onc(-c4ccc(OC)cc4)c2-3)cc1
b: CN(C(=O)COc1coc(CN2CCN(c3ccccc3)CC2)cc1=O)c1ccccc1
Answer: a. CCOc1ccc(-c2nc3c(s2)CCc2onc(-c4ccc(OC)cc4)c2-3)cc1
