Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(COC(=O)/C=C/c1cccc([N+](=O)[O-])c1)NCC1CCCO1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a: 20.437
b: 7.295
c: 4.412
d: 15.994
Answer: c. 4.412\%.
