The correct function used to insert data into a stack data structure is called Push. A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. This means that the last item inserted into the stack is the first one to be removed.

When we want to add or insert an element to the top of the stack, the Push operation is used. This adds the new item above the current top element, making it the new top of the stack.
