Task: Answer the MCQ question.
Question: Which compound exhibits a 13.691\% 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] O=C(Nc1ccccc1F)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
[b] O=C(CN(C1CCCCC1)S(=O)(=O)c1ccc(Cl)cc1)NCc1cccnc1
[c] CS(=O)(=O)/C(C#N)=C/c1cccn1S(=O)(=O)c1ccccc1
Answer: a. O=C(Nc1ccccc1F)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
