Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES O=C(Nc1cccc2c1CCCC2)c1cc([N+](=O)[O-])ccc1Cl?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) -0.620
b) -10.503
c) 17.808
d) 16.464
e) 4.549
Answer: a. -0.620\%.
