Can a (concrete) noun be parallel to a gerund ?
Sure—as long as there aren't any easily available ways to write the sentence with
better parallelism.
The bigger issue here, though, is that there are at least 2
VERY general principles that should stop you from asking this question:
1/
The problems are multiple-choice!You know this, of course—but you should take a moment here and there to think through the consequences more fully. One such consequence is that
you will never need to know when you can write imperfectly parallel structures, because you can just COMPARE THEM TO THE OTHER CHOICES. If another answer choice creates perfect parallelism (between the elements that actually should be parallel!), then eliminate the choice(s) with imperfect parallelism.
If no such thing happens in any other answer choice, then don't make those eliminations.
That's it.

GMAT SC does not test insanely specific subtleties.At some point, you should take a few moments to do two things:
——Look over a list of grammar topics that are actually tested in GMAT SC; notice that they're all major, fundamental aspects of written English that you'll find on almost every single page of any suitably formal text.
——Just think for a sec about how crazy it would be for something THIS specific to actually
impact people's business-school admissions! No respectable school would accept a test that differentiated between test takers on the basis of such trifles.
The explicit answer to your question is yes, by the way. The most common setup for this type of parallelism is the creation of nouns from 2 different verbs.
...because...
• SOME verbs have
dedicated noun forms that are NOT just _ing constructions working an extra shift.
e.g.,
destruction (from "to destroy");
approval (from "to approve");
addition (from "to add")
...but...
• Other verbs do not have such noun forms—requiring you to just use the _ing form instead.
e.g.,
pouring (as in "the pouring of concrete"; there's no word like pouration, pourage, or anything else like that)
So, you could have a sentence about, say,
"the pouring of concrete and the subsequent addition of chemicals to make it solidify quickly".
It's impossible to make those two words any more perfectly parallel. You don't need to determine that, though—you would just glance through the other answer choices and notice that the parallelism is either identical or worse in all four.
