Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.501% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCO[C@H]1OC(C(=O)O)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
b O=C(Cc1ccccc1)NNC1CC(=O)N(c2ccc(Br)cc2)C1=O
Answer: a. CCO[C@H]1OC(C(=O)O)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_10uM#}{herg_central_at_10uM__units} {herg_central_at_10uM__names__noun}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{SMILES%herg_central_at_10uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCO[C@H]1OC(C(=O)O)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
CCO[C@H]1OC(C(=O)O)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
