Out of the options given, cash at bank is the most liquid asset.
Liquidity refers to how easily and quickly an asset can be converted into cash without losing its value. In other words, it is the ability of an asset to be turned into cash quickly and easily.
Cash at bank is the most liquid asset because it can be easily accessed and used to pay for goods and services or to meet financial obligations. Other assets like land and buildings, machinery, goodwill, and furnitures and fittings are not as easily convertible to cash.
Land and buildings, for example, may take a long time to sell and may not fetch a fair price in an emergency situation. Machinery may also take time to sell and may not be in high demand when it is put up for sale. Goodwill, which is the intangible value of a business, cannot be sold separately from the business, and it may take time to find a buyer for the business.
Furnitures and fittings may be sold quickly, but they may not fetch a fair price in an emergency situation. Therefore, cash at bank is the most liquid asset out of the options given because it is readily available and easily convertible to cash when needed.
