Which one of these is the best description of a defined contribution plan?

A defined contribution plan is a retirement savings plan where both employees and employers can contribute a specified amount or percentage of the employee's salary into individual accounts. The final benefits received depend on the contributions made and the investment performance of those contributions over time. Unlike defined benefit plans, which guarantee a specific payout at retirement, the risk and potential reward in defined contribution plans are borne by the employee. Examples include 401(k) and 403(b) plans.
