Task: Answer the multiple choice question.
Question: Which compound has a -0.566\% 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(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])N1CCC(Cc2ccccc2)CC1
[b] Clc1ccc(-n2nnnc2-c2ccno2)cc1
[c] O=S(=O)(CCc1nnc(-c2ccccc2)o1)c1ccc2ccccc2c1
Answer: c. O=S(=O)(CCc1nnc(-c2ccccc2)o1)c1ccc2ccccc2c1
