Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.441\% 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) N/C(Cc1ccccc1Sc1ccccc1)=N\O.O=C(O)/C=C\C(=O)O
b) CCOC(=O)NC(=O)/C(C#N)=C/c1ccc(N(C)C)cc1
Answer: a. N/C(Cc1ccccc1Sc1ccccc1)=N\O.O=C(O)/C=C\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#}
N/C(Cc1ccccc1Sc1ccccc1)=N\O.O=C(O)/C=C\C(=O)O
N/C(Cc1ccccc1Sc1ccccc1)=N\O.O=C(O)/C=C\C(=O)O
