Explanation

Let's analyze each option:

Option A: Incorrect. Python uses def keyword to define functions, not function. This is JavaScript/other language syntax.

Option B: Incorrect. While the function definition is correct (def add_integers(x, y)), it uses print(x + y) instead of return x + y. The function prints the result but doesn't return it, so it returns None.

Option C: Incorrect. The function definition is correct but lacks a return statement. The expression x + y is evaluated but not returned, so the function returns None.

Option D: CORRECT. This option has the correct function definition with def keyword and properly returns the sum using return x + y. Note that there's a typo in the function name (add integers instead of add_integers), but the question asks for a code block to complete the task, and this is the only one with correct Python syntax and proper return statement.

Key Python concepts:

• Functions are defined using def keyword
• The return statement sends a value back to the caller
• Without return, a function returns None
• Function names cannot contain spaces in Python (though this appears to be a typo in the question)
