The answer is "FACE 4". As inner printf will print the "FACE" directly but when outer printf comes there is a %d mentioned which means integer value. So, the length of FACE is returned that is 4.

printf and scanf returns an integer. most of the time we don't save or use that integer. btw printf returns the number char it printed and scanf returns the number of input it too. like printf("arif") will return 4.
so printf(“​ %d​ ”,printf(“​ FACE​ ”)); this line does something like this....
1. as there is a %d format specifier, it goes after the comma ( , ) to look for the interger
2. there it found a function call that is printf("face"); , so it executes it.
3. and that printf return 4, so it comes back and prints 4 in place of that %d.

int x = printf("face");
printf("%d",x);
these two line will do the same thing.
