Task: Answer the multiple choice question.
Query: Which compound has a 13.635\% 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] CN(/N=C/c1ccc(-c2ccc([N+](=O)[O-])cc2)o1)c1ccccc1
[b] COc1cccc(NC(=O)CSc2nc3c(oc4ccccc43)c(=O)[nH]2)c1
[c] COC(=O)c1ccc(N2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)c([N+](=O)[O-])c1
[d] O=C(Nc1ccccc1)c1nsnc1C(=O)Nc1ccccc1
[e] O=C(Cc1ccc(Br)cc1)Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
Answer: a. CN(/N=C/c1ccc(-c2ccc([N+](=O)[O-])cc2)o1)c1ccccc1
