Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.790\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CCOC(=O)c1sc(=NC(=O)c2cc(OC)c(OC)c(OC)c2)n(C)c1C
(b) CCOC(=O)/C(C#N)=C/N1CCOCC1
(c) Nc1nc(-c2ccc(Cl)cc2Cl)cn1N
Answer: b. CCOC(=O)/C(C#N)=C/N1CCOCC1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
