The correct answer is D) canceling cable television and switching over to a monthly streaming network.
If you are trying to improve your budget and spending, the option that would save you the most money is "canceling cable television and switching over to a monthly streaming network."
When you have a tight budget, the first things you need to cut are unnecessary things. Your priorities are important and necessary things such as healthy food, rent, school, transportation, and medicine. No cable tv or streaming network, or expensive non-necessary purchases. Once you recover from the tight budget situation, you can again think about those things.
