Question

Anu Bhardwaj · Accepted Answer

A. It is a collection of data items that are unordered and unique.

Unordered: The items in a set do not have a specific index or order.
Unique: A set can only contain one instance of any given item. Duplicate items are automatically discarded.

Let's look at why the other options are incorrect:

B. It is used to hold together multiple related objects. This is a general description that could apply to many data structures, such as lists, arrays, or dictionaries, and is not specific enough to define a set.
C. It is a data structure that holds ordered collections of related data. This describes an ordered data structure, such as a list or an array, where elements are stored and retrieved by their index.
D. It is sometimes referred to as associative arrays in other languages. This is an incorrect statement. An associative array, also known as a dictionary or map, stores data as key-value pairs, which is a different concept from a set.
