B: THE CONTACT is effected continuously as opposed to A SERIES
C: THE CONTACT is effected continuously in contrast with A SERIES
In these answer choices, a reader might construe that THE CONTACT is being compared to A SERIES -- an illogical comparison.
Eliminate A, B and C.
E: is effected CONTINUOUSLY as against BEING at a series of points
Here, being serves as the object of the preposition against.
The object of a preposition must be a NOUN.
An adverb such as continuously cannot be compared to a noun such as being.
Eliminate E.
The correct answer is D.
D: The contact is effected CONTINUOUSLY rather than AT A SERIES OF POINTS.
Here, one adverb (continuously) is compared to another (at a series of points).
This comparison makes sense.
Note the following:
To show PREFERENCE in a comparison, the GMAT tends to use rather than.
I discuss the difference between instead of and rather than here:
