Stack is a data structure that follows the LIFO (last in first out ) pattern, and queue follows FIFO (first in first out) pattern.
Let's analyze the statements one by one -
Let's analyze the statements one by one -
Statement 1 - Dequeue is referred to as a double-ended queue, which is an advanced version of the queue, Not a stack( as per the ques ), Dequeue allows insertion and deletion at both end. but that's the property of queue, not stack. In stock, we have access to the top of the element only. We can insert and delete from one end only in the stack. So, This statement is false.
Statement 2 - Queue is an ordered linear data structure because it follows a particular order in insertion and deletion. And it follows FIFO ( first in first out) strategy, which means the element inserted first should come out first. So, this statement is TRUE.
Statement 3 - In python, we do not care about creating the front and rear pointer. Python is a dynamic language, so, it does not ask to create a list for the queue. We can use the INSERTREAR, INSERTFRONT function to implement front and rear in python. So, this statement is true.
Only Statement 1 turns out to be false here, So, option C will be the answer.

Explanation:
In order to determine which statement(s) is/are false, let's examine each statement individually.
Statement 1: Deque is a version of stack, which allows insertion and deletion at both ends.
This statement is true. Deque (Double Ended Queue) is a data structure that allows insertion and deletion at both ends. It can be visualized as a combination of a stack and a queue, where elements can be added or removed from either the front or the rear.
Statement 2: Queue is an ordered linear data structure, following FIFO strategy.
This statement is true. Queue is a linear data structure that follows the FIFO (First In, First Out) strategy. This means that the element inserted first will be the first one to be removed.
Statement 3: In Python, the use of predefined methods takes care of Front and Rear.
This statement is false. In Python, there are no predefined methods specifically for handling the front and rear of a queue. However, Python provides various built-in data structures and methods that can be used to implement a queue, such as lists or the collections.deque class. It is the responsibility of the programmer to handle the front and rear operations using appropriate methods or techniques.
Therefore, the correct answer is option C - Only Statement 1 is false.
