An application writes to a log file in the /logs filesystem that is full. After the log file is deleted，‘df’ still shows the filesystem as 100% full. What is the likely cause of the problem and what will resolve it？（）
- AThe deleted file is still open by the application. The system must be rebooted before ‘df’ will show the reduction in the filesystem.
- BThe deleted file is still open by the application. The application must be stopped before ‘df’ will show the reduction in the filesystem.
- CThe filesystem is still marked as full in the /etc/fs.status file. The system must be rebooted before ‘df’ will show the reduction in the filesystem.
- DThe filesystem is still marked as full in the /etc/fs.status file. The application must be stopped before ‘df’ will show the reduction in the filesystem.
