Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.023\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cc1nonc1OC(C)CNCCNc1ccc([N+](=O)[O-])cc1.Cl
b Cc1cccc(OCC(=O)Nc2nccs2)c1C
c O=C(Cn1cnc2ccccc21)N/N=C/c1cccc([N+](=O)[O-])c1
d CCOc1ccc(NC(=O)CC2C(=O)N(c3ccc(OCC)cc3)C(=S)N2C2CC2)cc1
e O=C1CCc2cc(S(=O)(=O)N3CCC(C(=O)NC4CCCc5ccccc54)CC3)ccc2N1
Answer: c. O=C(Cn1cnc2ccccc21)N/N=C/c1cccc([N+](=O)[O-])c1
