Final answer:
Having a savings account is a form of investment because it earns interest over time.
Step-by-step explanation:
The correct answer is b. Having a savings account.
A savings account can be considered a form of investment because it allows your money to earn interest over time. By depositing money into a savings account, you are essentially lending that money to the bank, which then pays you interest on your deposit. This interest acts as a return on your investment.
For example, if you deposit $1,000 into a savings account with an annual interest rate of 5%, you will earn $50 in interest over the course of a year. This means that your initial deposit has grown by 5%.
