Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES CN1C=CC2=C(C#N)C(N)C(C#N)(C#N)[C@H](c3ccccc3)[C@H]2C1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a 10.306
b 1.271
c 9.230
Answer: b. 1.271\%.
