Final answer:

When we add an item to a stack, it is known as a push operation, and when we remove an item, it is called a pop operation. The correct pair from the options is 1) Push, Pop.

Step-by-step explanation:

When we add an item to a stack, we call the operation a push. When we remove an item from a stack, we call that operation a pop. So the correct answer is 1) Push, Pop.

In computer science, a stack is a collection that is based on the last-in-first-out (LIFO) principle. When an element is added, it goes to the top of the stack, and this action is known as a push operation. Conversely, when an element is removed, it is taken from the top of the stack, and this is known as a pop operation. These operations allow stacks to be a useful data structure in various programming situations, such as in expression evaluation and backtracking algorithms.
