Consider this Swift code inside a view controller:
let detailVC = UIViewController()
detailVC.view.backgroundColor = .red
navigationController?.pushViewController(detailVC, animated: true)
What is the expected behavior when this code executes?
AThe app will crash because the view controller is not initialized properly.
BThe current view controller is replaced without animation.
CA new view controller with a red background is pushed onto the navigation stack and displayed.
DNothing happens because pushViewController is not called correctly.
