Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.219% 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 other words.
Options:
[a] COc1cccc(C(c2c(N)n(C)c(=O)n(C)c2=O)C(C)[N+](=O)[O-])c1
[b] O=C1CCC([N+](=O)[O-])C(c2cc3c(cc2Cl)OCO3)N1
Answer: b. O=C1CCC([N+](=O)[O-])C(c2cc3c(cc2Cl)OCO3)N1
