Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES CCCCN1C(=O)C(=O)N(CC(=O)Nc2cccc(C(C)=O)c2)C1=O?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: 8.762
b: -20.736
c: 2.418
d: -0.340
e: 9.665
Answer: a. 8.762%.
