Task: Answer the MCQ question.
Question: Which drug exhibits a 13.594\% 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.

[a] N#C/C(C(=O)NCc1ccco1)=C1/SC(Cc2ccc(F)cc2)C(=O)N1c1ccccc1
[b] COc1ccc(Cc2nc3c4c(ncn3n2)Oc2ccc3ccccc3c2C4c2ccc(OC)c(OC)c2)cc1
[c] CCCOc1cccc(C(=O)NCCNC(=O)c2ccc(C)nc2)c1
[d] CS(=O)(=O)N1CCN(c2ccccc2F)CC1
[e] O=C1Nc2ccccc2C1=Nc1cccc([N+](=O)[O-])c1
Answer: e. O=C1Nc2ccccc2C1=Nc1cccc([N+](=O)[O-])c1
