Task: Answer the multiple-choice question.
Query: Which compound has a -10.341% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] N#CCc1ccc(OC(=O)c2cccnc2)cc1
[b] CCOC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccc([N+](=O)[O-])cc1
[c] COc1ccc(NCc2nnc(-c3ccccc3)o2)cc1
[d] Cc1c(O)c2ccccc2oc1=O
[e] Cc1ccc2nc3c(cc(C(=O)NCc4ccco4)c(=N)n3Cc3ccco3)c(=O)n2c1
Answer: b. CCOC(=O)CN1C(=O)C(O)=C(C(C)=O)C1c1ccc([N+](=O)[O-])cc1
