They can sometimes get an extra job or stop spending on things they don’t need
The correct answer is B. Bob and Joe got into Joe's car.
Option A. and C. do not have a verb present, so it is not a sentence. Option D. does have a verb; however, it does not specify the car into which they got in, unlike option B..
I believe the answer is "D" because it describes the noun as late.
Hope this helps!!
