Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.354\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOc1ccc(C(CC(=O)O)NC(=O)COc2ccccc2OC)cc1OC
b: CC1CN(CCOc2ccccc2[N+](=O)[O-])CC(C)O1.O=C(O)C(=O)O
c: Fc1ccc(OCc2cc(-c3ccccc3)no2)cc1
d: Cc1nc(-c2cccc(Cl)c2)n[nH]1
e: O=C1COc2ccc(C(=O)c3ccccc3C(=O)NCc3ccccc3)cc2N1
Answer: b. CC1CN(CCOc2ccccc2[N+](=O)[O-])CC(C)O1.O=C(O)C(=O)O
{#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#}
CC1CN(CCOc2ccccc2[N+](=O)[O-])CC(C)O1.O=C(O)C(=O)O
CC1CN(CCOc2ccccc2[N+](=O)[O-])CC(C)O1.O=C(O)C(=O)O
