Task: Answer the multiple-choice question.
Question: Which drug has a 9.496\% 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:

[b] O=C(COc1ccccc1[N+](=O)[O-])NCCCN1CCCC1=O
[c] CC(C)Oc1ccc(C2CC(=O)N(c3ccc(C(=O)O)cc3)C2=O)cc1
[d] CC1CN(C(=O)CCC(=O)NCc2ccccc2)c2ccccc2S1
[e] Cc1nnsc1C(=O)NC1CCCc2c1cnn2-c1cc(F)cc(F)c1
Answer: b. O=C(COc1ccccc1[N+](=O)[O-])NCCCN1CCCC1=O
