Problem statement: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES O=C(COC(=O)c1ccc([N+](=O)[O-])s1)Nc1cccc(S(=O)(=O)NC2=NCCCCC2)c1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] -18.511
[b] 24.578
Answer: a. -18.511%.
