Task: Answer the multiple choice question.
Question: Which compound has a 12.934\% 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 COc1cc(NC(=O)CSc2nccc(C)n2)c(C)cc1[N+](=O)[O-]
b CCOc1ccc(CN2CCNC(=O)C2CC(=O)NC2CCCCCC2)cc1
c Cc1cccc(NC(=O)CSc2nnc(-c3ccncc3)n2C)c1
d O=C(COc1cc(F)ccc1[N+](=O)[O-])Nc1cccc(Br)c1
Answer: d. O=C(COc1cc(F)ccc1[N+](=O)[O-])Nc1cccc(Br)c1
