Answer 1

A queue is a FIFO data structure that removes an item from the front and has a front and a back.

Step-by-step explanation:

A queue is a data structure that follows the concept of FIFO (First-In-First-Out). It is commonly used to store elements in the order they are added and remove them from the front. Queues have a front and a back, where the front is the position of the next element to be removed, and the back is the position where new elements are added.

A queue does not have a LIFO (Last-In-First-Out) behavior like a stack. Therefore, the statements 'is a LIFO data structure' and 'removes and adds an item to the top' are incorrect.

The correct properties of a queue are: removes an item from the front, is a FIFO data structure, and has a front and a back.
