Problem statement: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES O=C(CSc1ccc(Cl)cc1)Nc1nnc(-c2cccc([N+](=O)[O-])c2)s1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a 13.316
b 5.923
c 5.064
Answer: a. 13.316\%.
