Task: Answer the multiple-choice question.
Question: Which compound has a 9.804\% 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] O=C(Nc1ccc(Cc2ccncc2)cc1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
[b] O=C1NC(=S)N/C1=C\c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])c(Cl)c1
Answer: b. O=C1NC(=S)N/C1=C\c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])c(Cl)c1
