The correct answer is D. All of the above.
The requirement of working capital depends on the period of operating cycle, the size of the business, and the turnover of current assets.
The period of operating cycle is the length of time it takes for a business to convert its inventory into cash. The longer the period of operating cycle, the more working capital is required.
The size of the business is also a factor in determining the requirement for working capital. Larger businesses typically have more inventory and receivables, which require more working capital to finance.
The turnover of current assets is the number of times a business’s current assets are converted into cash during a period. A higher turnover of current assets means that a business is able to generate more cash from its current assets, which reduces the need for working capital.
In conclusion, the requirement of working capital depends on the period of operating cycle, the size of the business, and the turnover of current assets.
