Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES O=C(c1cccc(C(=O)N2CCN(c3ccccc3F)CC2)n1)N1CCN(c2ccccc2F)CC1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a) -4.023
b) 23.966
c) 9.736
Answer: a. -4.023\%.
