Task: Answer the multiple choice question.
Query: Which compound exhibits a 11.816\% 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, b, or c without using any other words.
Options:
a) Br.C#CCOC(=O)C1=CCCN(C)C1
b) COC(=O)C1C(O)=CC(=O)CC1C
c) C=CCn1c(C(c2ccccc2)c2ccccc2)n[nH]c1=S
Answer: b. COC(=O)C1C(O)=CC(=O)CC1C
{#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#}
COC(=O)C1C(O)=CC(=O)CC1C
COC(=O)C1C(O)=CC(=O)CC1C
