JuniqueLidI humbly disagree with you on this point.
In my opinion, a question can be called low quality only if
X - The correct choice is reasonably flawed
Y - Incorrect choices may reasonably be considered to be correct answers
As correctly pointed by you, Choice A,B,C and E are flawed, and thus correctly, they are Incorrect!!
Thus this question does not fall under category Y for sure.
Coming to correct answer, lets examine the choice D
(D) Provide incentives to the city’s residents to reuse, rather than discard for pickup by the city’s service vehicles, whatever they can. - The root cause of problem is scarcity of transport vehicles. Question explicitly says its not possible to increase the number of both disposal and recycle transport trucks. In such a scenario, reducing the need for disposal/ recycle is a very viable option. As D mentions this, D is the correct answer!!
Also, in your comment you have mentioned "
However, what if reusable materials account for only a negligible proportion of what people dispose of - that is, people are more incentivised to reuse but they simply can't."On GMAT, even a 0.0000001% reduction is a reduction. So even though the plan mentioned in option D may not be 'very effective', it does solve the problem a little bit, and definitely in a better manner than other choices.
Open to listen your point of view on this!!

Personally think this is a very low quality question as all the possible answer options have flaws. Specifically:
(A) Provide larger recycling containers to the residents of the city.
>> Recycling container size may not be the root cause - people may be incentivised to get rid of rubbish, recyclable or not, as frequent as as possible which caused more recyclable materials be dumped for landfills. Weak contender.(B) Establish a community program to increase awareness of the benefits of recycling.
>> Awareness is not necessarily the root cause, either. People could be well-aware of the benefits and practising recycling but inconvenience caused by the reduced pickup frequency made it impractical to recycle. Weak contender.(C) Establish additional recycling centers as near as possible to the city’s residential areas.
>> True that if more recycling centers are conveniently accessible, people may be more incentivised to drop off rather than wait for pick up. However, it can still be a hassle for people such that people don't do so. Besides, the physical feasibility of available space to place new facilities, and the possibility that the nearest facility is still 100miles away can hinder people's willingness to do dropoffs.(D) Provide incentives to the city’s residents to reuse, rather than discard for pickup by the city’s service vehicles, whatever they can.
>> Sure, as the OA suggests, regardless of the reason for "supply" issue on the waste services side, addressing the "demand" size by reducing overall volume of disposing should help. However, what if reusable materials account for only a negligible proportion of what people dispose of - that is, people are more incentivised to reuse but they simply can't.(E) Ease restrictions on the types of materials the city’s service vehicles will pick up for transport to its recycling center.
>> Regardless of the restrictions, the city isn't picking them up. This is unlikely to help much.
