What is a Package in Python?
In Python, a package is a way of organizing related modules into a single directory hierarchy. A package is essentially a directory that contains a special file named __init__.py, which can be empty or contain initialization code for the package.
Analyzing the Options

Option A:
init.py- This is not the correct file name for a package initialization file in Python.

init, which is not the standard naming convention for a package initialization file.
- This is incorrect because it has only one underscore before and after
-
Option D:
init- This is incorrect because it lacks the
.pyextension and the double underscores.
- This is incorrect because it lacks the
Conclusion
The correct answer is:
B. __init__.py
This file is used to mark a directory as a Python package and can contain initialization code for the package.
