A fictitious asset is an asset that does not have any physical existence but is recorded on the balance sheet of a company. Out of the options given, "preliminary expenses" can be considered a fictitious asset.
Preliminary expenses refer to the expenses incurred by a company in the early stages of its formation or expansion, such as legal fees, registration fees, and expenses related to issuing shares. These expenses are not tangible assets like machinery or investments but are still recorded as assets on the balance sheet.
However, it is important to note that preliminary expenses are not a realizable asset, meaning they cannot be converted into cash or sold. They are treated as intangible assets and are gradually written off over a period of time.
