• The firm's financing requirements can be separated into D) seasonal and permanent.

The financing requirements may include current liabilities, long term funds, fixed assets, etc. but are classified as seasonal and permanent. Seasonal requirements can be related to sales increases and decreases, payment of large liability such as rent, tax, etc.

Let's analyze other options too:

A) current liabilities and long-term funds - The current liabilities are a direct financing requirement rather than a source.

B) current assets and fixed assets - The current assets and the fixed assets are present as a result of the financing source and are not financing the source themselves.

C) current liabilities and long-term debt - In addition to debt, there are many other financing sources such as equity which form the permanent financing source.
