Answer:
B.
Explanation:
A and C have awkward sentence structure because "when a car needs many serious repairs, it might be cheaper to buy a new car", it repeats the word car again making it redundant and in C, "When a car had needed many serious repairs, it might be cheaper to buy a new one", it has wrong use of past-tense.
The answer is c. A restatement in your own words; I think of it as a summary. Comes from Greek, meaning to modify the way something is told.
