Task: Answer the multiple-choice question.
Question: Which drug has a 14.861\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CC2)[C@@H]1CCCO
[b] O=c1c2c([nH]c3ccc(Br)cc13)CCCC2
[c] COC(=O)C1CCN(C(=O)COC(=O)C2CCN(S(=O)(=O)c3c(Cl)cccc3Cl)CC2)CC1
[d] CC1(C)NC(=O)N(CC(=O)N2CCN(c3cccc(Cl)c3)CC2)C1=O
Answer: a. CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CC2)[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_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__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_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CC2)[C@@H]1CCCO
CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CC2)[C@@H]1CCCO
