Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CCOC(=O)C1=C(C)N=c2s/c(=C/c3ccc(OCC(=O)O)c(OC)c3)c(=O)n2C1c1ccc(Cl)cc1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: 3.291
b: 19.885
c: 4.629
d: -2.771
e: 4.058
Answer: a. 3.291%.
