Task: Answer the multiple choice question.
Question: Which compound has a 12.793\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CN1C=CC2=C(C#N)C(N)C(C#N)(C#N)C(c3ccccc3)C2C1
b: C(=N/N1CCN(c2ccccn2)CC1)\C1=C(N2CCOCC2)/C(=C/c2ccccc2)CC1
c: COc1ccc(OCc2cccc(C(=O)Nn3cc([N+](=O)[O-])cn3)c2)cc1
Answer: b. C(=N/N1CCN(c2ccccn2)CC1)\C1=C(N2CCOCC2)/C(=C/c2ccccc2)CC1
