Which statement describes dynamic disks in a PC that is running Windows 10 Pro?

• They have the ability to create volumes that span across more than one disk.
• Free space can only be added from the same disk to extend the volume.
• A partition created on a dynamic disk can be shrunk without deleting the partition first.
• More space can be added to a partition by extending it into adjacent, unallocated space, as long as it is contiguous.
  

  Explanation: A dynamic disk has the ability to create volumes that span across more than one disk. The size of the partitions can be changed after they have been set, even if the unallocated space is noncontiguous. However, the partition size cannot be reduced without loss of data.
