Which of the Following Statements Most Accurately Describes the Benefits

Which of the following statements most accurately describes the benefits realized from Windows XP's policy of file caching simply by mapping files into the system's virtual address space?

A) The only advantage is that the physical memory used by the file cache can grow or shrink dynamically, depending on memory needs.
B) The only advantage is that this policy permits Windows XP to maintain separate caches for each mounted file system.
C) The only advantages are that the physical memory used by the file cache can grow or shrink dynamically depending on memory needs, and this policy permits Windows XP to synchronize data access between memory-mapped file access (which goes through the VMM) and traditional file access using read and write (which goes through the file system)
D) This permits physical memory used by the file cache to grow or shrink dynamically, depending on memory needs; this allows Windows XP to maintain separate caches for each mounted file system; and this permits Windows XP to synchronize data access between memory-mapped file access (which goes through the VMM) and traditional file access using read and write (which goes through the file system) .
