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=C(NC(=S)N1CCN(c2ccc(Cl)cc2[N+](=O)[O-])CC1)c1cccs1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:

b) 7.841
c) -3.016
d) 15.931
Answer: a. -29.956%.
