Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.979\% 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) CCCCOc1ccc(/C=C(\C#N)C(=O)NC2CC2)cc1
b) C/C(CC(=O)Nc1ccccn1)=N\NC(=O)c1cnccn1
Answer: b. C/C(CC(=O)Nc1ccccn1)=N\NC(=O)c1cnccn1
{#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}?
