Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CCN1CCN(C(=O)N(Cc2ccc(Cl)cc2)S(=O)(=O)c2ccc(C)cc2)CC1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] -12.461
[b] -8.875
Answer: a. -12.461\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
