Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.989% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccccc1N(CC(=O)NCCSCc1ccccc1)S(C)(=O)=O
b Cc1ccc(C(=O)c2cc(C)sc2N)cc1
c Cc1cc(OCC(=O)N2CCOCC2)ccc1NC(=O)c1ccccc1C
d CC(=O)/C(N=Nc1cc2c(cc1[N+](=O)[O-])OCCO2)=C(\C)O
Answer: d. CC(=O)/C(N=Nc1cc2c(cc1[N+](=O)[O-])OCCO2)=C(\C)O
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_10uM#}{herg_central_at_10uM__units} {herg_central_at_10uM__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_10uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CC(=O)/C(N=Nc1cc2c(cc1[N+](=O)[O-])OCCO2)=C(\C)O
CC(=O)/C(N=Nc1cc2c(cc1[N+](=O)[O-])OCCO2)=C(\C)O
