# Which set is a subset of every set? {} {0} {1}

A set is a well-defined collection of numbers, alphabets, objects, or any items. A subset is a part of the set.

## Answer: The trivial subset of every set is {}.

Let's understand the properties of a subset in detail.

**Explanation:**

Set A is a subset of set B if all the elements in set A are present in set B. Here, A is called the subset, and B is called the superset. It is denoted by A⊆B.

- An empty set is a subset of every set.
- {} is a subset of every set.
