Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES COCCn1c(-c2ccc(C#N)cc2)nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: -33.936
b: 2.672
c: 2.362
d: 3.280
e: -1.021
Answer: a. -33.936%.
