Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.029\% 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 additional words.
Options:
a COc1ccc(-c2csc3nc(C(C)C)oc(=O)c23)cc1OC
b Br.CCOC(=O)C(CC)(CCC(=O)OC)c1csc(Nc2ccccc2O)n1
c Cc1nc(-c2nc(-c3c(C(=O)NNC(=O)c4ccc(Cl)cc4)noc3C)cs2)cs1
d CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](C2CCCCC2)[C@H]1CCCO
Answer: d. CCO[C@@H]1OC(C(=O)NC2CC2)=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)NC2CC2)=C[C@H](C2CCCCC2)[C@H]1CCCO
CCO[C@@H]1OC(C(=O)NC2CC2)=C[C@H](C2CCCCC2)[C@H]1CCCO
