Answer 2

The real-world scenario that could be associated with a stack data structure is, the "piling up of chairs one above the other". (option 1st)

• The Stack data structure can be defined as a linear kind of data structure, in which the principle followed is LIFO (Last In First Out). A Stack has just one end, compared to the queue, which has two.
• Now, it can be seen that among the given scenarios, only the first one, that is, "piling up of chairs one above the other", will follow the order of last in first out, as the chair that is put at last, will be taken out first. So, it is similar to the Stack.
• Thus, the correct answer will be option first.
