Task: Answer the multiple-choice question.
Question: Which compound exhibits a 14.643\% 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] COc1cccc(/C=N/NC(=O)c2nc(-c3ccccc3)cc(-c3ccccc3)n2)c1
[b] CC(NC(=O)c1ccco1)C(=O)N1CCN(c2ccccc2)CC1
[c] CCOc1ccccc1CNC(=O)c1nn(CC)cc1[N+](=O)[O-]
[d] O=C(NC(Cc1ccccc1)C(=O)O)/C(=C/c1ccccc1)NC(=O)c1ccc(Br)o1
[e] O=C(CNS(=O)(=O)c1ccc(F)c(Cl)c1)N1CCCC1
Answer: c. CCOc1ccccc1CNC(=O)c1nn(CC)cc1[N+](=O)[O-]
