Task: Answer the multiple choice question.
Query: Which drug has a 9.948\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
b) CN(Cc1ccccc1)C(=O)Cn1c(=O)oc2cc(S(=O)(=O)N3CCCC3)ccc21
c) CCc1ccc(OCc2nnc(SCC(=O)N3CCN(c4ccccc4)CC3)o2)cc1
Answer: a. CCO[C@H]1OC(C(=O)NCc2ccccc2)=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)NCc2ccccc2)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
CCO[C@H]1OC(C(=O)NCc2ccccc2)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
