Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.466\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(CCc1ccccc1)NCCCN1CCOCC1
b) COc1cc(NC(=O)C/C(C)=N/NC(=O)C(OC)c2ccccc2)c(OC)cc1Cl
c) CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1c(C)nn(-c2ccccc2)c1Cl
d) Cc1ccc(C(=O)NC2CC(C)(C)NC(C)(C)C2)c(C)c1
Answer: c. CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1c(C)nn(-c2ccccc2)c1Cl
{#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}?
