Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.370\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CCOC(=O)C1=NNC(C(=O)c2ccc(Cl)cc2)C1c1ccc(OC)cc1
[b] O=C(Nc1nccs1)c1cccc(S(=O)(=O)N2CCCCC2)c1
[c] O=C(COc1ccc(/C=N/NC(=O)c2cc3ccccc3o2)cc1Br)Nc1ccccc1
[d] O=C(c1ccc(Cl)cc1[N+](=O)[O-])N(Cc1ccccc1)Cc1ccccc1
[e] O=C(Cn1ncc2c1-c1ccccc1OC2)N(Cc1ccco1)C1CCCCC1
Answer: d. O=C(c1ccc(Cl)cc1[N+](=O)[O-])N(Cc1ccccc1)Cc1ccccc1
