Answer - B - Flash drives should be removed from the computer using the Safely Remove Hardware icon in the notification area.

Key Takeaway: A USB drive has a file system, just like a hard drive does. If the power to the machine is cut, or the drive is pulled out during a write, this will result in incomplete data and possibly a corrupted file system on the drive. The "Safely Remove Hardware" bit calls for all programs accessing the drive to complete whatever reads or writes they are performing, as the drive will be removed. When all I/O is complete, the OS removes the drive from its list of usable drives and then tells you it's safe to remove it.
