Answer: A
window.history.pushState(newPageState, '', null);: This method updates the current history entry with newPageState without reloading the page or changing the URL visibly.
Back Button Behavior: When the user clicks the browser's back button after pushState has been called, the browser navigates back to the previous history entry.
popstate Event: This event is fired on the window object when the active history entry changes. If the user navigates back after pushState, a popstate event is triggered.
State Property: The popstate event includes a state property that contains the state object associated with the history entry. In this case, newPageState passed to pushState will be available as event.state in the popstate event handler.
