Correct option is C
The correct answer is (C).
Detailed Analysis
- The Error: "...to cut back for expenses to..."
- The Rule: The phrasal verb "cut back" (meaning to reduce) requires the preposition "on" when identifying what is being reduced.
- The Correction: The correct idiom is "cut back on [something]." Additionally, the second preposition needs to be "to" (infinitive of purpose) to explain why they are cutting back (to save money).
- Corrected Sentence: Due to the recent financial downturn, the family decided to cut back on expenses to save money for unexpected emergencies.
Why the other options are incorrect:
- (A) to cut back on expenses for: While "cut back on" is correct, "for save money" is grammatically incorrect. "Save" must be in the infinitive form ("to save").
- (B) to cut back by expenses to: "By" is used for the amount of reduction (e.g., "cut back by 10%"), not the category being reduced.
- (D) to cut back in expenses on: "Cut back in" is not the standard idiomatic expression for reducing spending.
- (E) No correction required: Incorrect, because "cut back for" is not the correct idiomatic usage.
