Which of the following is not a type of retirement account?

A savings account is not classified as a retirement account because it serves a different primary purpose. While a savings account is a standard financial product offered by banks and credit unions that allows individuals to deposit money and earn interest, it is designed for general savings needs and immediate liquidity.

In contrast, retirement accounts such as an Individual Retirement Account (IRA), a 401(k), and pensions have specific tax advantages and regulations that encourage long-term savings specifically for retirement. These accounts are structured to help individuals save over time while often providing benefits like tax deferments or employer matching contributions in the case of a 401(k). Each of these retirement savings vehicles is explicitly intended to provide for financial stability during retirement, making them fundamentally different from a savings account.
