Which type of thing can be enjoyed without altering its substance?

The correct answer is a nonconsumable thing. A nonconsumable item is one that can be enjoyed and used without being consumed or depleted in the process. This means that the essence or substance of the item remains intact after use. For example, a piece of furniture can be utilized for sitting or decoration, and using it does not diminish its physical existence.

In contrast, consumable things are items that are used up or consumed during enjoyment, such as food or drink, where the physical substance is altered completely after use. Intrinsically derived things and real property do not specifically fit the criteria in the context of this question, as they do not inherently describe the ability to enjoy something without altering its substance. Intrinsically derived things could include various entities based on their nature, but their connection to being nonconsumable may not be as clear. Real property, while generally enduring, is not categorized in the same way as nonconsumable things in relation to this question.
