Solution

A. It is used for object serialization

Explanation

Pickling is the process of serializing and deserializing a Python object structure. In Python, the pickle module provides a way to serialize Python objects into a format that can be saved to a file, transmitted over a network, or otherwise stored for later use. The serialized data can later be deserialized, reconstructing the original Python object hierarchy.
