(A) geeksforgeeks
(B) geeksquiz
(C) geeksforgeeks geeksquiz
(D) Compiler Error
Answer: (B)
Explanation: Note that arr[] is static in fun() so no problems of returning address, arr[] will stay there even after the fun() returns and all calls to fun() share the same arr[].
strcpy(fun(), str); // Copies "geeksforgeeks" to arr[] str = fun(); // Assigns address of arr to str strcpy(str, "geeksquiz"); // copies geeksquiz to str which is address of arr[] printf("%s", fun()); // prints "geeksquiz"
