Task: Answer the multiple-choice question.
Question: Which compound has a 21.390% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. O=C(COc1ccc(Cl)cc1)NCCNc1ccc([N+](=O)[O-])cc1
b. COCCOC(=O)C1=C(N)Oc2c(c(=O)oc3ccccc23)C1c1ccncc1
c. CCOC(=O)C1=C(C)N(CCCC(=O)O)C(=O)NC1c1cc2ccccc2c2ccccc12
d. CCOc1ccccc1OC(=O)c1cc2ccccc2oc1=O
e. O=[n+]1cc(-c2ccc(Cl)cc2)n([O-])c2c1CCC2
Answer: e. O=[n+]1cc(-c2ccc(Cl)cc2)n([O-])c2c1CCC2
