Global variable are available to all functions. Does there exist a mechanism by way of which

Answer : Option B
The only way this can be achieved is to define the variable locally in main() instead of
defining it globally and then passing it to the functions which need it.
Suppose a program is divided into three files f1, f2 and f3, and a variable is defined in the file
f1 but used in files f2 and f3. In such a case would we need the extern declaration for the
variables in the files f2 and f3?
