Task: Answer the multiple choice question.
Question: Which compound has a -3.978\% 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 additional words.
Options:
[a] O=C(c1cc(-c2ccc(Cl)cc2)n(-c2cc(Cl)ccc2Cl)n1)N1CCOCC1
[b] COCC(C)n1c(=O)sc2ccccc2c1=O
Answer: a. O=C(c1cc(-c2ccc(Cl)cc2)n(-c2cc(Cl)ccc2Cl)n1)N1CCOCC1
