Which of the following statements are correct about the C#.NET code snippet given below? Stack st = new Stack(); st.Push("hello"); st.Push(8.2); st.Push(5); st.Push('b'); st.Push(true);

• Dissimilar elements like "hello", 8.2, 5 cannot be stored in the same Stack collection.
• Boolean values can never be stored in Stack collection.
• In the fourth call to Push(), we should write "b" in place of 'b'.
• To store dissimilar elements in a Stack collection, a method PushAnyType() should be used in place of Push().
• This is a perfectly workable code.
