Which of the following set of statement is correct ?

1. typedef long a;
  extern int a c;
2. typedef long a;
  extern a int c;
3. typedef long a;
  extern a c;
4. None of the above

Correct Option: C

In the second statement the a will be replaced by its data type.
So
Option A will be extern int long c;
Option B will be extern long int c;
Option C will be extern logn c;

So here only option C is correct.
