Answer: ``` def add_integers(x, y): return x + y ```
## Explanation Option D is the correct answer because: 1. **Correct function definition syntax**: Python uses `def` keyword to define functions, not `function` keyword (which is used in other languages like JavaScript). 2. **Proper return statement**: The function uses `return x + y` to actually return the sum to the caller. 3. **Case-sensitive variable names**: It uses consistent lowercase `y` variable (not uppercase `Y`). **Why other options are incorrect**: - **Option A**: Uses `function` keyword instead of `def` - this is not valid Python syntax. - **Option B**: Uses `function` keyword and lacks a return statement - the function would return `None`. - **Option C**: Uses `print()` instead of `return` - this prints to console but doesn't return the value to the caller. - **Option E**: Has a typo with uppercase `Y` (should be lowercase `y`) and lacks a return statement. **Key Python concepts**: - Functions are defined with `def function_name(parameters):` - The `return` statement sends a value back to the caller - Python is case-sensitive (`y` ≠ `Y`) - `print()` outputs to console but doesn't return a value for further processing
