What distinguishes 'consumable' items from 'durable' items in materiel management?

The distinction between consumable items and durable items in materiel management lies primarily in their usage and lifespan. Consumable items are characterized by their intended use, which is often to be used up or depleted during operations or activities. This means that consumable items require replenishment once they are exhausted, such as supplies like office materials, food items, or cleaning products.

On the other hand, durable items are designed for long-term use and often have a significantly longer lifespan. They can be reused multiple times without being consumed in the process, such as tools, machinery, or furniture. This fundamental difference is crucial in managing inventories effectively, as the strategies for ordering, stocking, and budgeting for these two types of items will vary accordingly.

Thus, the correct answer accurately captures the essence of how these items are classified based on their consumption and longevity within the materiel management framework.
