Which best describes this axiom:

$($ aList $.$ insert $($ i$,$ item $)).$ remove $($ i $)=$ true

You can only remove an item from a list at the position you last inserted an item

None of these

After inserting an item in an existing list at a position i$,$ an item can be removed from that position

Removing an item from an existing list at the last position one was inserted is not possible
