Solution:
The given sequence of items is 1, 2, 3, 4, 5.
We can implement the given problem using a stack data structure. We can push the items onto the stack until we encounter the number 3. After encountering 3, we can pop the items from the stack and print them. Finally, we can print the remaining 2 items in the sequence.
Let's see the step-by-step procedure to solve this problem:
1. Initialize an empty stack.
2. Read the input sequence of items.
3. Push each item onto the stack until we encounter the number 3.
4. After encountering 3, pop the items from the stack and print them until the stack becomes empty.
5. Print the remaining 2 items in the sequence.
Let's apply the above steps to the given input sequence:
1. Initialize an empty stack.
2. Read the input sequence of items: 1, 2, 3, 4, 5.
3. Push each item onto the stack until we encounter the number 3: Stack = {1, 2}.
4. After encountering 3, pop the items from the stack and print them until the stack becomes empty: Stack = {}, Output = {2, 1}.
5. Print the remaining 2 items in the sequence: Output = {2, 1, 4, 5}.
Therefore, the output sequence is 5, 4, 3, 2, 1, which is option 'C'.
Hence, the correct answer is option 'C'.

The item can be pushed to stack and later popped and printed, or printed directly.
If 1, 2, 3, 4, 5 is the input, then (4) is not possible because once pushed, 1 is printed after 2.
Similarly, (1) and (2) are not possible.
If 1, 2, 3, 4, 5 is the input, then (4) is not possible because once pushed, 1 is printed after 2.
Similarly, (1) and (2) are not possible.
