Task: Answer the multiple choice question.
Question: Which drug has a 8.391\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Nc1cc([N+](=O)[O-])ccc1Cl)C1CC1
b: COC(=O)c1ccc(N2CCN(S(=O)(=O)c3c(C)cc(C)cc3C)CC2)c([N+](=O)[O-])c1
c: N#Cc1ccc(Oc2cccc(C(=O)O)c2)cc1C#N
Answer: a. O=C(Nc1cc([N+](=O)[O-])ccc1Cl)C1CC1
