I do not recall any official question in which the modifying phrases of two parallel elements were this far apart in structure.
Although I believe that this sentence lacks parallelism because "commencing with . . ." is present, Answer A is still the best.
I am happy to stand corrected on the parallelism issue.
These sentences are hella hard to write. Try writing just one.
At the same time, we do not want to get too clever by half.

am I missing something about parallelism in this instance?
You are treating parallel structure as more convention based and less logic based than it is.
Except in cases that are governed by certain specific conventions, elements of a list do not have to be structurally the same. They just have to work together logically, and, therefore, they have to have the same functions.
So, for instance, the following sentence is just fine:
The red car without a front bumper and the, unfortunately, quite damaged racing car were loaded onto the trailer.
We have two elements of a list:
"the red car without a front bumper"
"the, unfortunately, quite damaged racing car"
Both of these expression represent things. Both things can be loaded onto a trailer. The sentence makes perfect sense.
There are very few situations in which elements of lists are not considered parallel unless they match in a way that goes beyond their basic functions.
One convention that - one could argue - goes beyond logic is the convention of using all gerunds or all infinitives. Either of the following would be considered correct:
I like to swim and to play volleyball.
I like swimming and playing volleyball.
The following is logical enough, but is deemed incorrect, basically just because people have decided that it is.
I like to swim and playing volleyball.
That convention is an exception, however.
In most cases, anything goes, as long as the structure of a list is logical.
Therefore, since the list in the version created via the use of choice (A) is logical, there is no parallel structure related issue.
All that said, occasionally, a Sentence Correction question writer will create question that involves, debatably illogically, a choice between structures, all of which are parallel, but one of which is more perfectly parallel than the others. So, you may see a question in which two versions are basically correct, and the only clear difference is that one is more perfectly parallel than the other. If you really have such a choice to make, go with the more parallel version.
Of course, you have to be careful, because, another thing that Sentence Correction question writers do is make the most parallel choice an incorrect choice.
