Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.925\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC1(C)C(c2cccs2)=[N+]([O-])C2(CCCCC/C2=N\NC(N)=O)N1O
b. COc1ccccc1CNCc1cc(OC)c(OC)c(OC)c1.O=C(O)C(=O)O
Answer: a. CC1(C)C(c2cccs2)=[N+]([O-])C2(CCCCC/C2=N\NC(N)=O)N1O
{#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}?
