Question $2[2$ marks$]$

Implement an extension method for ObservableCollection class to add all elements in a List to the end of the ObservalableCollection object. Test the implemented extension method. SinglyLinkedList

Show in the image:

Implement a C# application to consume the implemented SinglyLinkedList. More specifically, load the data from Auto$\_$mpg$.$csv and store those data into a singly linked list.

$1.$ Insert data line by line, the insertion can be occurred at the head of your singly linked list, or at the end of your singly linked list

$2.$ print out all elements in the singly linked list in a good format $($e$.$g$.,$ one line per vehicle$).$
