The correct answer is D.
OBJ-5.5: The best option in this scenario is to uninstall and reinstall the stock market app. When apps are updated automatically, they can sometimes become faulty or corrupted and slow down performance on the device. With Android phones, much like iPhones, apps can run in the background and may begin to take up excess resources. If the app is removed, the phone is rebooted, and the app is reinstalled, and the issue persists, then the app should be removed, and an alternate app selected to replace it.
