Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.310\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(O/N=C\c1ccc(N2CCOCC2)c([N+](=O)[O-])c1)c1ccc(F)cc1
[b] COc1ccc(C(=O)Cc2cnn(-c3ccccc3)c2)c(O)c1
[c] Cc1ccc(C)c(-n2nnnc2SCC(=O)Nc2cccc(-c3nnc4n3CCCCC4)c2)c1
[d] CCc1nnc2n1N=C(c1ccc([N+](=O)[O-])cc1)CS2
[e] CCCCCn1c(=O)c(F)cn(Cc2ccc(OC)c([N+](=O)[O-])c2)c1=O
Answer: e. CCCCCn1c(=O)c(F)cn(Cc2ccc(OC)c([N+](=O)[O-])c2)c1=O
