Which of the following best describes the function of the glycogen debranching enzyme in glycogenolysis?

B)It cleaves $\alpha$(1$\to$6)branch points releasing glucose-1-phosphate.
C)It cleaves $\alpha$(1$\to$6)branch points releasing glucose.
D)It transfers an $\alpha$(1$\to$4)linked trisaccharide unit to the nonreducing end of an alternate branch,then cleaves the $\alpha$(1$\to$6)branch point releasing glucose-1-phosphate.
E)It transfers an $\alpha$(1$\to$4)linked trisaccharide to the nonreducing end of an alternate branch,then cleaves the $\alpha$(1$\to$6)branch point releasing glucose.
