Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.435\% 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 additional words.
Options:
a O=C1CC(c2ccccc2Cl)CC(O)=C1C=NCCCO
b OC(C#CCCN1CCCCC1)(c1ccccc1)c1ccccc1
c N#CC1(NC(=O)CSc2nnc(Cc3ccccc3)o2)CCCCC1
Answer: a. O=C1CC(c2ccccc2Cl)CC(O)=C1C=NCCCO
{#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#}
O=C1CC(c2ccccc2Cl)CC(O)=C1C=NCCCO
O=C1CC(c2ccccc2Cl)CC(O)=C1C=NCCCO
