Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a compound with the SMILES O=C(Nc1ccc2c(c1)C(=O)OC2)c1ccc(Cl)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a: 20.652
b: -42.340
c: 20.519
Answer: a. 20.652%.
