Answer 1

Correct choice is (a) No string boundary checks in predefined functions For explanation I would say: The strcat(), strcpy(), sprintf(), gets() etc when called in C and C++ can be exploited because these functions don’t check whether the stack is large enough for storing the data fetched from some other variable holding larger data.
