Answer : Option C

Explanation :

Declaration: char *strrchr(const char *s, int c);

It scans a string s in the reverse direction, looking for a specific character c.

Example:

#include  
#include  

 int main(void) 
 {  
      char text[] = "I learn through FresherGate.com";  
      char *ptr, c = 'i';    

     ptr = strrchr(text, c);    
     if(ptr)     
        printf("The position of '%c' is: %d\n", c, ptr-text); 
     else    
        printf("The character was not found\n");  
      return 0; 
 }
