Let me address you doubt in the following few lines.
Due to the highly selective nature of admissions, the admissions committee
has been recommended to prevent the passing of feedback to the students.A) has been recommended to prevent the passing of feedback to the students.
B) have been recommended to prevent the passing of feedback to the students.
C) has been recommended to prevent them from passing feedback to the students.
D) have been recommended in an attempt to prevent them from passing feedback to the students.
E) has been recommended that they prevent the passing of feedback to the students
First thing is that one should not bother about the non-underlined part unduly except to find some clues about the error. Whether 'due to' phrase was good or bad, you needn't worry because the author doesn't want you to worry. Otherwise, she would have certainly underlined it. This exercise is just to see whether you can get the S-V number and the pronoun number agreements right.
Now to come to the difference between 'due to' and 'because of', they are both prepositional phrases and what follows the two words will always be a noun or a gerund. This noun does not decide whether the modifier modifies a noun or a verb.
You must see what the nature of the sentence is after the entire modifier is separated from the modified main clause.
Due to the highly selective nature of admissions, the admissions committee has been recommended to prevent the passing of feedback to the students. --- The main clause here consists of a verb 'has been recommended'; therefore, the modifier starting with 'due to' wrongly modifies a verb. Therefore, this structure is grammatically wrong.
On the contrary, if you want write a sentence with 'due to' as a correct modifier in the same sentence, then you may rephrase it as follows.
Due to the highly selective nature of admissions, the admissions committee was given a
recommendation to prevent…
Now you can see that 'due to' correctly modifies the noun 'recommendation'
Some more examples
His late
arrival was
due to the engine failure
Here the adjectival phrase 'due to' modifies the noun 'arrival.'
It will be wrong to say that the he arrived late due to the engine failure.
Similarly, it will be wrong to say that his arrival was delayed because of engine failure.

The last word -- 1. The use of 'due to' in students' admission committee question is grammatically wrong.
2. Gmatclub test example is okay as I see.
3. Adverbial modifiers can be anywhere in the sentence not necessarily close to the verb they modify.
3. Please practice the concept of due to and because of vigorously.
4. If I remember rightly,
Magoosh has some good examples on this topic.
