Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.156\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: C/C(=N\NC(=O)CSCc1ccc(Cl)cc1)c1ccc(NC(=O)c2ccccc2)cc1
b: C/C(O)=C(\N=Nc1cc(C)ccc1O)C(N)=O
Answer: b. C/C(O)=C(\N=Nc1cc(C)ccc1O)C(N)=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}?
