Task: Answer the multiple choice question.
Query: Which compound has a 7.700\% 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] COC(=O)Cc1c(O)ccn(Cc2cccc3ccccc23)c1=O
[b] Cn1c(SCc2ccc(Cl)cc2)nc(C(F)(F)F)cc1=O
Answer: a. COC(=O)Cc1c(O)ccn(Cc2cccc3ccccc23)c1=O
