Task: Answer the multiple-choice question.
Question: Which compound has a 2.714\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](c2csc3ccccc23)[C@H]1CCCO
b.) Oc1ccccc1/C=N/Nc1cc(N2CCCC2)nc(N2CCCC2)n1
c.) O=C(N/N=C/c1c[nH]c2ccc(Br)cc12)c1ccccn1
d.) O=C(Nc1cc2c(cc1Cl)OCCCO2)c1ccc(F)cc1
Answer: a. CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](c2csc3ccccc23)[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](c2csc3ccccc23)[C@H]1CCCO
CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](c2csc3ccccc23)[C@H]1CCCO
