which investment has the least liquidity?\nmutual fund\nhouse\nchecking account\nsmall business

Brief Explanations:

Liquidity refers to how quickly an asset can be converted to cash without significant loss in value. A house typically takes a long - time to sell and may require significant costs and negotiations, making it less liquid compared to a mutual fund (which can be sold relatively quickly), a checking account (from which cash can be withdrawn immediately), and a small business which may also have more complex and time - consuming selling processes but generally less so than a house in terms of the real estate market's nature.
