A
function add_integers(x, y): return x + y
B
function add_integers(x, y): x + y
C
def add_integers(x, y): print(x + y)
D
def add_integers(x, y): return x + y
E
def add_integers(x, y): x + y

Explanation
Option D is correct because it properly defines a Python function using the def keyword and returns the sum of the two integers using the return statement.
Let's analyze each option:
Option A: Incorrect - Uses function keyword instead of def keyword. Python uses def to define functions, not function.
Option B: Incorrect - Uses function keyword instead of def and doesn't return the result. The function would execute x + y but wouldn't return anything.
Option C: Incorrect - Uses correct def keyword but prints the result instead of returning it. The function would display the sum but wouldn't return it for further use in the program.
Option D: Correct - Uses proper Python syntax with def keyword and returns the sum using return statement.
Option E: Incorrect - Uses correct def keyword but doesn't return the result. The function would calculate x + y but wouldn't return it.
In Python, functions must be defined with the def keyword, and to make the result available to the caller, you need to use the return statement. Without return, the function either returns None (if no return statement) or only prints to console (if using print()).
