Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.379\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CC(C)CN(C(=O)CN1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
b CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccc(C(F)(F)F)cc2)[C@H]1CCCO
Answer: b. CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccc(C(F)(F)F)cc2)[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(N)=O)=C[C@H](c2ccc(C(F)(F)F)cc2)[C@H]1CCCO
CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccc(C(F)(F)F)cc2)[C@H]1CCCO
