Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.658\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCOc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(OC)cc2)cc1OC
b) O=C(COc1ccc(-c2ccccc2)cc1)N/N=C/c1ccccc1Br
Answer: a. CCOc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(OC)cc2)cc1OC
{#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#}
CCOc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(OC)cc2)cc1OC
CCOc1ccc(C2NC(=O)C(C#N)=C(S)N2c2ccc(OC)cc2)cc1OC
