There are two cases here:
FIRST:: if( printf(""))
printf("Face");
else
printf("Focus");
If these is case then output should be Foucs, AND it is not given in the option.

SECOND CASE: if( printf(" ")) //space inside printf statement
printf("Face");
else
printf("Focus");
In second case the output should be _Focus.... where _ represents space.

Actually the built-in function printf( ) returns the integer corresponding to number of characters it prints, now coming to your query

printf(“”);
Here printf returns 0 since, the count of characters it printed is 0.

‘’-0

if(0) is false ( if (any positive integer ) is always true )so the body of “else” will be executed.
