What is the scope of a variable?

  1. The number of times it can be accessed

  2. The range in the code where the variable can be used

  3. The memory space it occupies

  4. The data type it can hold

The correct answer is: The range in the code where the variable can be used

The scope of a variable refers to the range in the code where it can be accessed, used, and modified. This includes both the location in the code where it is defined and any other parts of the code where it can be referenced. It is important to note that a variable's scope is limited to the specific block of code or function in which it is declared, and it cannot be accessed from outside that scope. Additionally, while a variable's scope is determined by where it is defined, it is not affected by the data type it can hold, the memory space it occupies, or the number of times it can be accessed. Therefore, options A, C, and D are incorrect.
