Which of the following best describes the EPF?

The correct description emphasizes that the EPF, or Employees' Provident Fund, serves primarily as a retirement benefits scheme targeted at salaried employees. This scheme is designed to promote long-term saving by accumulating funds during an individual's working life, ensuring financial stability upon retirement. Contributions are typically made by both the employee and employer, which helps grow the retirement corpus over time. By focusing on the aspect of providing retirement security, this answer captures the main objective of the EPF.

In contrast, while there may be elements related to the other choices, they do not encapsulate the essence of what the EPF represents. For instance, the EPF is not a universal financial product available for everyone, nor is it solely aimed at private sector employees. Additionally, it is not primarily a fund for stock market investments; instead, it focuses on secure savings for retirement. This context illustrates why the other options do not accurately characterize the nature and purpose of the EPF.
