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 CC(=O)OCCn1c(Br)nc2c1c(=O)[nH]c(=O)n2C?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a 8.815
b 1.746
c 6.432
d 2.450
Answer: c. 6.432%.
