Which of the following best defines local scope?

Local scope refers to the accessibility of variables, functions, or methods that are declared within a specific function or block. When a variable is defined with local scope, it can only be accessed and manipulated within that particular function or block of code. This means that once the execution of the function or block is completed, the variable is no longer accessible from outside of it. This helps prevent variable name conflicts and unintended interference with variables defined in different areas of the code.

This concept is foundational in programming as it enhances modularity and maintainability, allowing programmers to write clearer and more organized code. The correct understanding of local scope is crucial for effective coding practices, as it ensures that data remains encapsulated and secure within its defined context.
