Which statement best describes a local scope variable?

• A. Only used for the block of code they are declared in.
• B. Global scope variables are accessible from anywhere.
• C. They are stored in a stack.
• D. They must be declared as constants.

Answer: (A)

Local scope means a variable is confined to the block of code where it’s declared. It comes into existence when that block runs and disappears when the block finishes, so it can’t be used outside of that block. That’s exactly what the statement is describing: the variable is only usable within its own block. For context, global variables live outside of blocks and can be accessed from anywhere in the program. The note about storage location—such as being on the stack—is common in many languages because local variables often follow the function’s call lifecycle, but it isn’t a universal rule across all languages. Also, local variables don’t have to be constants; they can be reassigned unless you explicitly declare them as constants.
