关于there be ron的回答：
there is nothing wrong with saying 'there is x'. this construction is basically equivalent to 'x exists' (if x is a thing), or 'x happens' (if x is an event).
the problem, though, is that "the intentional discarding of lens caps, packing material , fuel tanks and payload covers" IS the "littering".
so, sentences D and E are not logical.
because of' must be followed by SOMETHING ELSE that is actually the cause of something.
'with' should be followed by a component or part of the previous observation.
note that the correct answer is phrased in a way that removes this problem.
the correct answer says "orbits ... have become more and more littered". in this version, "littered" means roughly the same as 'dirty' or 'polluted'.
