The correct answer is scope.
A variable’s scope indicates where the variable can be used in an application code. It is the part of the program where the variable is defined and can be used. The scope of a variable is determined by its declaration.
For example, if a variable is declared in a function, then it can only be used in that function. If a variable is declared at the global level, then it can be used in any part of the program.
The scope of a variable is important because it helps to prevent errors. If a variable is used in a part of the program where it is not defined, then the program will not compile.
The other options are incorrect because they do not accurately describe the concept of scope.
- Lifetime is the period of time during which a variable exists in memory.
- Place is the location in memory where a variable is stored.
- Position is the location of a variable in the source code.
