None

In general knowledge, "none" refers to the absence of anything or the lack of a particular thing. It indicates that there are no items, options, or individuals present in a given context. For example, if someone asks how many apples are in a basket and the answer is "none," it means there are zero apples. "None" can also signify that a particular condition or characteristic does not apply. Essentially, it is a way to express emptiness or nonexistence in relation to specific subjects or items.
