Which of the following correctly describes how a function is called (invoked) in C?

Consider the following code:

struct node {

    int data;

    struct node *next;

};

struct node *head = NULL;

void insert(int data) {

    struct node *n = malloc(sizeof(struct node));

    n->data = data;

    n->next = head;

    head = n;

}

After executing:

insert(10);

insert(20);

insert(30);

}
