Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(c1cc(C(=O)N2CCN(c3ccc(F)cc3)CC2)cc([N+](=O)[O-])c1)N1CCN(c2ccc(F)cc2)CC1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a.) 4.843
b.) 5.184
c.) 8.835
Answer: b. 5.184\%.
