Identify the erroneous segment; choose ‘‘No error’’ if the sentence is correct. Sentence: They wanted money to purchase certain things for themselves and for donated to their colleagues.

Introduction / Context:
This sentence mixes prepositional structure with an incorrect verb form. After a preposition like ‘‘for,’’ a noun or gerund should follow, not a past participle used as in ‘‘for donated.’’ There is also a spelling slip in ‘‘themeselves,’’ but the heavier grammatical error is in the fourth segment.

Given Data / Assumptions:

• Parallelism intended: ‘‘for themselves and for … to their colleagues.’’
• Problem phrase: ‘‘for donated’’
• Purpose: to indicate giving money/items to colleagues

Concept / Approach:
After ‘‘for,’’ use a noun (‘‘donation’’) or a gerund (‘‘donating’’). Therefore, the correct forms are ‘‘for donation to their colleagues’’ or ‘‘for donating to their colleagues.’’ The past participle ‘‘donated’’ is wrong in this slot because no auxiliary creates a passive clause.

Step-by-Step Solution:
Maintain parallel structure: ‘‘for themselves and for donating to their colleagues.’’Correct word form: change ‘‘donated’’ → ‘‘donating’’ (or noun ‘‘donation’’).Optional secondary fix: correct ‘‘themeselves’’ → ‘‘themselves’’ in C.

Verification / Alternative check:
Try other prepositions: ‘‘for eating,’’ ‘‘for reading,’’ not ‘‘for eaten/for read,’’ which would be ungrammatical without a passive auxiliary.

Why Other Options Are Wrong:
A and B are fine. C contains a spelling error, but exams typically prioritise the major grammatical fault when two issues exist; D is the segment that clearly violates grammar rules.

Common Pitfalls:
Using past participles after prepositions; breaking parallelism in coordinated prepositional phrases.

Final Answer:
for donated to their colleagues.
