The correct option is C with GPS devices our ability to conceptualize space is eroded, with the Internet’s many hyperlinks we are driven to distraction, and with our smartphones our working memory is impaired
A) GPS devices eroding our ability to conceptualize space, the many hyperlinks of the Internet driving us to distraction, and with our smart phones our working memory is impaired - the three arms of the list are unparallel
B) GPS devices erode our ability to conceptualize space, the Internet’s many hyperlinks drive us to distraction, and our Smartphones impair our working memory very tempting to pass it as the right answer; while the three targets are stated forthwith after the colon, still the list is the doer of the modifier ‘when doing something as fundamental as recalling a string of digits’. This is contrary to the logic that it is the human beings who are the doers of the action. In that context, this is inferior to the C.
C) with GPS devices our ability to conceptualize space is eroded, with the Internet’s many hyperlinks we are driven to distraction, and with our smartphones our working memory is impaired - Maintains the discipline of parallelism while holding aloft common logic. But its verbosity is a distraction.
D) GPS devices erode our ability to conceptualize space, the Internet’s many hyperlinks driving us to distraction and our smartphones impairing our working memory - Unparallel
E) the conceptualization of space is eroded with GPS devices, distraction is driven by the Internet’s many hyperlinks, and working memory impairment results from our smartphones - unparallel with two passive voice and one active voice
