Answer : Option C

Explanation :

A label is used as the target of a goto statement, and that label must be within the same function as the goto statement.

Syntax: goto ;
Control is unconditionally transferred to the location of a local label specified by .
Example:

 #include  int main() {     int i=1;     while(i>0)     {         printf("%d", i++);         if(i==5)           goto mylabel;     }     mylabel:     return 0; }
