Task: Answer the multiple choice question.
Question: Which compound has a 14.341\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(O)c1ccc(Nc2ccc(Cl)c(Cl)c2)c([N+](=O)[O-])c1
[b] Oc1ccc(-c2nc3ccc4ccccc4c3c3c2CCC3)cc1O
[c] Cc1occc1C(=O)Nc1cccc([N+](=O)[O-])c1C
Answer: a. O=C(O)c1ccc(Nc2ccc(Cl)c(Cl)c2)c([N+](=O)[O-])c1
