The correct answer is that the variable maintains local scope. In programming, the scope of a variable refers to the context within which that variable is defined and can be accessed.

When you declare a variable within a function using the same name as a global variable, the local variable takes precedence within that function. This means that the local variable is restricted to that function's scope and cannot be accessed outside of it. It effectively "shadows" the global variable, meaning that any reference to that variable name within the function will refer to the local version rather than the global one.

This behavior is a fundamental aspect of variable scope in programming, allowing for encapsulation and preventing unintended interference between global and local variables. Therefore, understanding the concept of local scope is crucial, especially when working in environments where global variables may exist.
