Task: Answer the multiple choice question.
Question: Which compound has a -0.885\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CN(C(=O)COC(=O)c1ccc([N+](=O)[O-])cc1N)c1ccccc1
b Cc1ccc(CN(C(=O)c2ccco2)C(C(=O)NC2CCCC2)c2ccc(N3CCOCC3)cc2)cc1
c C=CCn1cc(C(=O)NCCOC)c(=O)c2cc(S(=O)(=O)N3CCCCCC3)ccc21
d CCc1c(O)nc(SCC(=O)NCc2ccco2)[nH]c1=O
Answer: a. CN(C(=O)COC(=O)c1ccc([N+](=O)[O-])cc1N)c1ccccc1
