Assume that the Node class is defined as

$```$

class Node $\{$

int data;

Node next;

$\}$

$```$

Consider the function $\backslash ($ f $\backslash )$ below.

$```$

boolean f $($ Node n $)\{$

if $($n $==$ null $)$

return false;

if $($ n$.$next $==$ null $)$

return false;

Node p $=$ n;

while $($ p$.$next $!=$ null $)\{$

if $($p$.$data $$ p$.$next.data$)$

return false;

p $=$ p$.$next;

$\}$

return true;

$\}$

$```$

If $\backslash ($ f $\backslash )$ is called with a head reference of a linked list, it returns true if $...$

not all elements in the list have the same value of data

the list has more than one element and the elements in the list are sorted in a nondecreasing order $($from smallest to largest, but some values could be equal$)$ the list has more than one element and the elements in the list are sorted in a nonincreasing order $($from largest to smallest, but some values could be equal$)$

the list has only one element

none of the above
