c - sorting name, surname, id alphabetical order with using only a singly linked list

Question

Example image

I have a struct like the given below:

struct Student
{
    char *name;
    char *surname;
    long int ID;
    struct Student *name_next;
    struct Student *surname_next;
    struct Student *ID_next;
}

I need to sort according to alphabetical order of name and besides that alphabetical order of surname and also sort according to ID. But I can only use a single linked list, not three lists. How can I do that?
