Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES O=C1C=C(c2ccccc2)C[C@H](c2cccs2)[C@H]1n1nnc([N+](=O)[O-])n1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:

(b) 1.639
(c) -19.752
Answer: c. -19.752%.
