Question 19 of 200.0 5.0 PointsSelect a collection type that match all condition bellow : it is implemented as a circular buffer. It follows LIFO (last in first out ) system. it is a weakly typed collection. Push method allows you to add items to it Peek method just gets the last object of it Pop method also get the last object and then removes that item from it A. Stack Class B. Queue Class C. HashTable Class D. Array class Question 20 of 200.0 5.0 PointsSelect a collection type that match all condition bellow : It is useful for storing messages in the order they were received for sequential processing. it maintains FIFO (first in first out) system. With it you can create weakly typed collections that are ordered by the order they are added to the collection. It accepts a null reference as a valid value and allows duplicate elements. Objects stored in it are inserted at one end and removed from the other. A. Queue Class B. Array class C. Stack Class D. HashTable Class
