Task: Answer the multiple-choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES CCCCCN(C(=O)COC(=O)CSc1ccc([N+](=O)[O-])cc1)c1c(N)n(CCCC)c(=O)[nH]c1=O?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] -40.540
[b] -0.163
[c] 0.573
Answer: a. -40.540%.
