Which type of variable is created when passing by value in a function?

When a function is called with an argument passed by value, a copy of the original variable is created. This means that any modifications made to the variable inside the function will not affect the original variable outside the function. The original variable remains unchanged because the function operates on the new copy. This behavior is fundamental in programming and helps prevent unintended side effects, ensuring that the function can manipulate its parameters without altering the state of the variables that were used to call it.

Reference variables and global variables do not get created in this context as the function is provided with a temporary copy rather than a direct reference to the original or a shared global state. Thus, the correct answer reflects this key concept of how parameters are managed in functions that utilize pass-by-value semantics.
