Explanation

Let's analyze each option:

Option A: function add_integers (x, y): - This is incorrect because Python uses def keyword to define functions, not function.

Option B: def add_integers (x, y): print(x + y) - This is incorrect because the function prints the result but doesn't return it. The requirement is to "return the sum", not just print it.

Option C: def add_integers (x, y): x + y - This is incorrect because the function doesn't have a return statement. In Python, if there's no return statement, the function returns None.

Option D: def add integers (x, y): return x + y - This is CORRECT. It uses the proper Python syntax:

• def keyword to define a function
• Function name add_integers (note: there's a space in the text, but this appears to be a typo in the question - the function name should be add_integers without a space)
• Parameters (x, y)
• return statement to return the sum x + y

Note: There appears to be a typo in the question where Option D shows def add integers (with a space) instead of def add_integers. However, among the given options, Option D is the only one that has the correct structure with def and return statement.

Key Python Concepts:

1. Functions in Python are defined using the def keyword
2. The return statement is used to return a value from a function
3. Without a return statement, a function returns None by default
4. Function names should follow Python naming conventions (typically snake_case)
