Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES COc1ccc(C2=NCCn3nc4cc([N+](=O)[O-])ccc4c32)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: 5.386
b: 6.454
c: 15.538
Answer: a. 5.386\%.
