Problem statement: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES CCn1ncc(CN2CCN(Cc3ccc(OC)c(C)c3C)C(CCO)C2)c1C?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a -19.947
b 5.048
Answer: a. -19.947%.
