Two statements are given below, one is Assertion (A) and the other is ...
Assertion (A): Queue is a data structure that follows the First-In-First-Out (FIFO) principle.

Reason (R): The last item added to the queue is the first item to be removed from the queue.

The correct answer is option 'C' - A is correct, but R is not correct.

Explanation:

Queue:
A queue is a linear data structure that follows the First-In-First-Out (FIFO) principle. It is an abstract data type with two primary operations - enqueue and dequeue.

First-In-First-Out (FIFO) Principle:
The FIFO principle states that the item that is inserted first is the one that comes out first. In other words, the element that is added first to the queue will be the first one to be removed.

Assertion (A) Explanation:
The assertion (A) states that a queue is a data structure that follows the FIFO principle. This is correct because in a queue, elements are added at one end called the rear, and they are removed from the other end called the front. The element that has been in the queue for the longest time is at the front, and the element that has been added most recently is at the rear. Hence, the assertion is correct.

Reason (R) Explanation:
The reason (R) states that the last item added to the queue is the first item to be removed from the queue. However, this is not correct. In a queue, the first item to be removed is always the one that has been in the queue for the longest time, which is at the front. The last item added, which is at the rear, will be removed after all the items added before it have been removed. Hence, the reason is incorrect.

Therefore, the correct answer is option 'C' - A is correct, but R is not correct.
