Which of the following is an important step towards achieving financial security?

Having an emergency fund is a critical step toward achieving financial security because it provides a financial safety net for unexpected expenses or emergencies, such as medical bills, car repairs, or job loss. This fund allows individuals to handle unforeseen circumstances without resorting to high-interest debt or depleting savings that are earmarked for other purposes. An emergency fund typically contains three to six months' worth of living expenses, ensuring that a person can maintain their financial obligations even during difficult times.

In contrast, solely focusing on increasing income may not effectively address financial security unless paired with sound saving and spending habits. Similarly, imposing a strict budget can help manage expenses but does not directly prepare someone for sudden financial shocks. Avoiding all debt can be prudent, but some forms of responsible debt (like a mortgage or student loans) can help build assets and increase overall financial stability. Thus, establishing an emergency fund is foundational in securing one's financial future.
