What type of assets are defined as those that will be held or used for more than one year?

The correct choice identifies fixed assets, which are defined as long-term assets that a company will hold or use for more than one year. These assets are essential for the production of goods or services and are not intended for resale in the regular course of business. Common examples of fixed assets include property, plant, and equipment, which play a crucial role in a company's operations.

Current assets, on the other hand, are expected to be converted into cash or used up within one year, which sets them apart from fixed assets. Current liabilities are obligations that a company needs to settle within a year, while inventory assets represent goods available for sale or used in production, again typically within a short-term period. Thus, recognizing fixed assets as the correct answer reflects an understanding of asset classification based on the duration they will be utilized within a business's operational framework.
