Step-by-step explanation:

Concept= Set Theory

Given= Set of Principals in a school

To find= Which kind of set is this

Explanation=

Set is a collection of data or elements represented together in an organized manner.

There are many kind of sets according to the number of elements present in it.

Null Set= This is a set when no element is present in a set.

Singleton Set= In this set only one element or value is contained.

Finite Set= This set contains a fixed number of elements in it only.

Infinite Set= In an infinite set the number of elements are not fixed they are infinite.

We are given the set of Principals in a School.

We already know that a school can have only one principal. Therefore the set of principal will contain only one element and any set containing only one element is called Singleton Set.

So, the set of Principals in a school is Singleton Set.
