What is the correct way to create a for loop that iterates over a list named `items`?

The correct way to create a for loop that iterates over a list named items is to use the syntax for item in items:. This structure is fundamental in Python, where the keyword for is followed by a variable name (in this case, item) and the in keyword, which is used to specify the iterable (the list items).

This loop effectively assigns each element of the list items to the variable item one at a time, allowing for operations to be performed on each element within the body of the loop. This syntax is concise and adheres to Python's readability principles, making it easy to understand and maintain.

Other options present incorrect syntax. The use of "each," "all," or "loop" does not conform to the required structure of a for loop in Python, which specifically demands the format of for variable in iterable:. Therefore, option B is the only valid construction for iterating over a list in this context.
