Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES O=C(Nc1nc(-c2ccccn2)cs1)c1cc(Cl)ccc1[N+](=O)[O-]?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:

b: 15.109
c: 0.550
d: -18.435
e: 22.253
Answer: a. 12.488\%.
