B. Dictionary

C. Set

D. None of the Above

Correct Answer is :

C. Set

Explanation

Set in Python:

• A set is an unordered collection of unique elements.
• It does not allow duplicate values, which means each element in a set must be unique.
• Sets are mutable, meaning you can add or remove elements once a set is created.
• Sets are typically used when the existence of elements is more important than the order or how many times they occur.
