My answer is (D).

The subject of the sentence is singular "Research". Eliminate (A) owing to SVA issue with "have".

To present examples, use "such as" rather than "like". Eliminate (B).

To have apple-vs.-apple comparison, we eliminate (C) and (E) because it is not parallel to compare "the damage" with "information overload".
In addition, the past perfect tense in (E) cannot be justified without an explicit past event.

Moreover, the adverbial use of "due to" in this sentence is frowned upon in GMAT.

Research into information pollution—a term popularized by web usability experts—have determined that the impact of disruptive information pollutants such as unsolicited electronic messages (spam) is less than that caused by information overload due to the proliferation of social media platforms.

1)Subject "Research into information pollution" requires singular verb - Eliminate A for breaking SV agreement rule

2)to give example we use such as not like - Eliminate B

3)"That" in B and D refers to what ? Damage? if so sentence does not make a lot of logical sense ..

Research into information pollution—a term popularized by web usability experts—has determined that the damage caused by disruptive information pollutants such as unsolicited electronic messages (spam) is less than damage of information overload due to the proliferation of social media platforms.

4) Past perfect is not the right tense to use as there is no other action to match the sequencing of events -Eliminate E

Left with Option (C)

Ellipses explicitly replaced with phrases
Research into information pollution—a term popularized by web usability experts—has determined that the damage caused by disruptive information pollutants such as unsolicited electronic messages (spam) is less than "the damage caused by" information overload due to the proliferation of social media platforms.

There are some other issues in the non underlined part of sentence
1) "Due to" is an adjective and should not be used to modify a verb or give reason for some action
2) Role of phrase between hyphens is not very clear; does it modify "Research into information pollution" if so, the subject the entire phrase is a term and term by itself can not determine anything but the research can.

Looking forward to OE

- Research is a singular subject hence requires a singular verb HAS. ( Eliminate A )
- The tense used in option E is incorrect. ( Eliminate E )
- "Such as" is used to give out a list. Option B incorrectly uses like. ( Eliminate B )
- Option C incorrectly compares the impact of disruptive information pollutant to information overload. ( Eliminate C )

Answer : D

Easy elimination for A and E because in A (S-V disagreement) and in E (the use of past perfect is not justified here).
B - like
C - such as
D - such as
B is eliminated because spam belongs to information pollutants
C is eliminated because the lack of "that" (parallelism problem)
This leads to D.

Few differences across the options
1. has vs have vs had
2. such as vs like
3. less than vs less than that of

For #1 The correct usage is HAS as it relates back to 'research' which is singular.. A and e eliminate
For #2, the correct usage is 'such as' .. 'Like' is used to express similarity in most instances .. B eliminate
For #3, lets browse the options C and D

In C, 'damage caused by..' is compared to 'information overload..' So eliminate

Answer is D

BONUS: this sentence is correct usage of 'caused by' two ways to check this - 1. Replacing 'caused by' with 'due to' makes sense 2. 'Caused by' answers the question 'What'
Experts please correct if above understanding is wrong
Thanks!
