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 drug with the SMILES C=CCNc1nc(C)c(CNc2c(C)cc(C)cc2C)nc1C#N?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a.) -8.569
b.) 3.562
c.) 7.835
Answer: c. 7.835\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
