Step-by-step explanation:

Answer:
D. The bank balance in John's saving account increases from Month 4-5
Step-by-step explanation:
Lets go with one answer at a time
However, an entire $750 has changed therefore, option A would be incorrect.
When in fact it has changed more than $250 downwards, so option B would be incorrect.
However, in that time period it stays the same therefore, option C would also be incorrect.
Now that should mean that D is the right answer, but, we should still check.
Yes it does change upwards. It increases $750 again.
Therefore, your answer would be D. The bank balance in John's saving account increases from Month 4 to 5.
