Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES COC(=O)C1=CO[C@@H](O[C@@H]2OC(CO)[C@@H](O)[C@@H](O)[C@@H]2O)C2C1CC[C@]2(C)O?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a: -3.860
b: -0.251
Answer: b. -0.251%.
