need assistance with pop and push operations - stack

Question

I'm studying for a Microsoft Exam, one of the preparation questions is as follows:
You have a stack that contains integer values. The values are pushed onto the stack in the following order: 2,4,6,8.
The following sequence of operations is executed:
Pop,
Push 3,
Pop,
Push 4,
Push 6,
Push 7,
Pop,
Pop,
Pop,
What is the value of the top element after these operations are executed?
A. 2
B. 3
C. 6
D. 7
Correct Answer: B
Why is B the correct answer?

Answer 1

A stack is a LIFO (Last In First Out) structure. A "Pop" deletes the last thing you put on it.
2 4 6 8
Pop
2 4 6
Push 3
2 4 6 3
Pop
2 4 6
Push 4
2 4 6 4
Push 6
2 4 6 4 6
Push 7
2 4 6 4 6 7
Pop
2 4 6 4 6
Pop
2 4 6 4
Pop
2 4 6
For me, 6 is on the top (meaning the next element that would be popped out) of the stack at the end, so C would be the correct answer

Answer 2

Agree with the answer also... checking with code
namespace StackTest
{
class Program
{
static void Main(string[] args)
{
Stack st = new Stack();
// Starting
st.Push(2);
st.Push(4);
st.Push(6);
st.Push(8);
// Showing state
ShowStack(st,"Contenido inicial");
//Pop, Push 3, Pop, Push 4, Push 6, Push 7, Pop, Pop, Pop,
st.Pop();
ShowStack(st, "Quitar uno");
st.Push(3);
ShowStack(st, "Agregado 3");
st.Pop();
ShowStack(st, "Quitar uno");
st.Push(4);
ShowStack(st, "Agregado 4");
st.Push(6);
ShowStack(st, "Agregado 6");
st.Push(7);
ShowStack(st, "Agregado 7");
st.Pop();
st.Pop();
st.Pop();
ShowStack(st, "Quitar tres");
ShowStack(st,"Situacion Final");
Console.ReadKey();
// 2, 4 , 6 , 8
}
private static void ShowStack(Stack st,string message)
{
Console.WriteLine(message);
foreach (var item in st)
{
Console.WriteLine(item.ToString());
}
Console.WriteLine("-------------------");
}
}
}
