Task: Answer the multiple-choice question.
Question: Which drug has a 11.491\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc(N2CCN(CCNC(=O)Nc3ccc(C)c(Cl)c3)CC2)cc1
b: Cc1cc2c(cc(C(=O)OC(C(=O)NC3CCCCC3)C(C)C)n2C)o1
c: C=CCN=C1N[C@@H](c2ccccc2)C(C(=O)OC)=C(C)N1CC
d: CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](c2ccccc2)[C@H]1CCCO
Answer: d. CCO[C@@H]1OC(C(=O)Nc2ccccc2)=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_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)Nc2ccccc2)=C[C@H](c2ccccc2)[C@H]1CCCO
CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](c2ccccc2)[C@H]1CCCO
