Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.229\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CCN(CC)/C(N)=N/c1nc(C)cc(C)n1
b. Cc1ccc2[nH]c(=O)c(CN(c3cccc(C)c3C)S(=O)(=O)c3ccccc3)cc2c1
Answer: a. CCN(CC)/C(N)=N/c1nc(C)cc(C)n1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?

Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCN(CC)/C(N)=N/c1nc(C)cc(C)n1
CCN(CC)/C(N)=N/c1nc(C)cc(C)n1
