Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.877\% 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 other words.
Options:
a Cn1nc(C(=O)Nc2ccccc2N2CCCC2)c2ccccc2c1=O
b CC(C)(C)CC(=O)NC(=S)NCCc1ccccc1
c CCOC(=O)c1ccc(NC(=O)CSc2nnc(-c3ccncc3)n2C)cc1
d COc1cccc(-c2nn(-c3ccccc3)cc2C(=O)O)c1
e O=[N+]([O-])c1ccc(O)c(/C=N/Nc2ncnc3c2cnn3-c2ccccc2)c1
Answer: e. O=[N+]([O-])c1ccc(O)c(/C=N/Nc2ncnc3c2cnn3-c2ccccc2)c1
