Why the other choices are wrong
Choice A
Choice A is incorrect. The sentence compares dockless programs to docked programs, noting an advantage of docked programs: they offer order and consistency. It doesn’t compare disadvantages of the two types of programs.
Choice B
Choice B is incorrect. The sentence compares dockless programs to docked programs, noting an advantage of dockless programs: they are easy and inexpensive to implement. However, it misrepresents information from the notes, stating that dockless programs are less flexible than docked programs. In addition, it doesn’t compare disadvantages of the two types of programs.
Choice D
Choice D is incorrect. The sentence emphasizes an advantage of dockless programs, then makes a general statement that applies to both types of programs; it doesn’t compare disadvantages of the two types of programs.
