Question

Which XXX completes the following algorithm for inserting a new node into a singly-linked list?

ListInsertAfter(list, curNode, newNode) {
if (list⇢head == null) {
list⇢head = newNode
list⇢tail = newNode
}
else if (curNode == list⇢tail) {
list⇢tail⇢next = newNode
list⇢tail = newNode
}
else {
XXX
}
}
Group of answer choices
newNode⇢next = curNode⇢next
curNode⇢next = null
 
newNode⇢next = null
curNode⇢next = list⇢tail⇢next
 
newNode⇢next = curNode⇢next
curNode⇢next = newNode
 
newNode⇢next = curNode⇢next
curNode = newNode
