Answer:
The answer is C.
Step-by-step explanation:
Option C, take a second house mortgage, is least likely to help increase someone's net worth for that month. In fact, taking on more debt through a second mortgage would likely decrease one's net worth, as it increases liabilities and reduces the equity in one's home.Options A, B, and D are all more likely to help increase net worth. Saving and investing money can grow one's assets, paying down existing debt can reduce liabilities and increase net worth, and contributing toward a retirement account can help build wealth over time through compound interest and investment returns.
