Please explain why each statement is either right or wrong, thanks! :-)

Which of the given solutions is the correct output after executing the fun method on the linked list defined below. Note, we pass the first element 'f' of linked list defined below as a parameter to fun. Client code: var input = f - > r - > e - > d - > i - > v - > i - > d - > e - > r - > null: public Node fun(Node x) { Node first = x: Node magic = null: while (first != null) { Node second = first.next: first.next = magic: magic = first: first = second: } return magic: } f - > d - > r - > v - > r - > d - > null f - > v - > i - > r - > e - > d - > null d - > e - > r - > i - > v - > i - > r - > e - > d- > f - > null r - > e - > d - > i - > v - > i - > d - > e - > r - > f - > null

Explanation / Answer

corect ans is option d

r- e- d- i- v- i- d- e- r- f- null

since the code is reversing the linked list

since when the function is called

first = f

magic = null

then

second = first.next = r

first.next = magic = null

magic = first =r

first = second = r

and so on
