Explanation

Let's analyze each option:

Option A: Incorrect. Python uses def keyword to define functions, not function. The syntax is wrong.

Option B: Incorrect. Same issue as Option A - uses function keyword instead of def. Also, the function doesn't return anything explicitly.

Option C: Incorrect. While it uses the correct def keyword, it prints the result instead of returning it. The requirement is to "return the sum", not print it.

Option D: CORRECT. This uses the proper Python syntax with def keyword, takes two parameters x and y, and returns their sum using the return statement.

Option E: Incorrect. Uses correct def keyword but doesn't return the result. In Python, if you don't explicitly return a value, the function returns None.

Key Python concepts:

Functions in Python are defined using the def keyword
The return statement is used to return a value from a function
Without a return statement, a function returns None by default
print() outputs to console but doesn't return a value for further use in code
