There are various splits for this question, but I always choose subject-verb agreement since I feel quite at ease with it and it makes sense to me. For this question, it is quite helpful to rapidly scan the question at the outset to identify the different splits and select the one you feel most at ease with. You only need one split for this question if you choose subject-verb agreement as your first split.

Let’s check the options one by one -

Option A is incorrect:
A is an incorrect answer. We have a subject-verb agreement issue because "the gig economy" is supposed to be referred to by "them" (plural).
(Sidebar: You may argue that "them" refers to "think tanks" or any other plural noun, but this would be irrational given the meaning.)

Option B is incorrect:
Option B is the incorrect choice. We have a subject-verb agreement issue because "the gig economy" is supposed to be referred to by "them" (plural).

Choice C is incorrect:
Option C is incorrect. The plural form of "technologies" requires a plural verb, but this choice uses "is" (singular).

Choice D is correct:
D is the correct choice. No mistakes.

Choice E is incorrect:
This is the incorrect choice. Though it is really unusual from a meaning perspective, technology is not always bad. The gig economy makes use of a variety of technologies. It includes platform technologies like mobile app development and communication technologies like email and instant messages.
