Problem statement: 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 Cn1c(=O)c2c(nc(N3CCc4ccccc4C3)n2C)n(C)c1=O?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) -3.885
(b) 2.665
(c) 2.848
(d) 3.472
Answer: a. -3.885\%.
{#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#}?
