Task: Answer the multiple-choice question.
Question: Which compound has a 5.565\% 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(N/N=C/C=C\c1cccc([N+](=O)[O-])c1)c1ccccn1
b) CCn1c(=O)c([N+](=O)[O-])c(NCCN(C)C)c2ccccc21
c) Cc1ccccc1S(=O)(=O)Nc1nc2ccccc2nc1N1CCc2ccccc2C1
Answer: a. O=C(N/N=C/C=C\c1cccc([N+](=O)[O-])c1)c1ccccn1
