Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.731\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOC(=O)Cn1c(=O)cc(C)c2cccc(C)c21
b: Nc1nc(Nc2cccc(F)c2)nc(N2CCOCC2)c1[N+](=O)[O-]
c: CN1CCN(NC(=O)/C=C/c2cccc([N+](=O)[O-])c2)CC1
d: CCOC(=O)C1=C(C)NC(SC)=C(C#N)C1CC(C)C
e: COc1ccc(C(=O)OCCOc2ccccc2C(C)=O)c(O)c1
Answer: d. CCOC(=O)C1=C(C)NC(SC)=C(C#N)C1CC(C)C
{#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#}
