Consider a Stack element {1,2,3,4,5} given by below==>>
To Implement Queue using Stack we have three operation given as ===>
Operation 1.Reversing it we get====>>
Operation 2 Followed by Poping===>>
{1,2,3,4,5}
Operation 3 Followed by Enqueing===>>>
From the Above Diagram we can conclude that C) is true
