Which of the following is a valid way to append an element to a linked list in Python?

Step 1: Understand what a linked list is. A linked list is a data structure that consists of nodes, where each node contains a value and a reference to the next node.
Step 2: Know that in Python, linked lists are often implemented as classes. Each linked list class usually has methods to manipulate the list, including adding elements.
Step 3: Identify the method used to add an element to the end of the linked list. This method is commonly called 'append'.
Step 4: Recognize the syntax for calling the append method. You would use the name of the linked list object followed by a dot and then 'append(value)'.
Step 5: Conclude that if you have a linked list object named 'linked_list', you can add an element by writing 'linked_list.append(value)'.
