You administer storage for an application "myapp" on server QA1, with a file system dedicated to code and configuration data for that myapp. Part of the testing discipline is to return myapp's file system to a known initial state prior to each test activity, and to run a series of tests beginning with the same initial state. The traditional approach to preparing for each test involves restoring the file system from a backup image prior to each test, which imposes an hour's delay between the end of one test run and the beginning of the next.A typical testing session lasts only two to three hours, the hour of restore delay between tests reduces the availability of the server for testing by about 30%.What kind of Storage Foundation mechanism would work best to reduce the delay required between tests?

A. Third-mirror breakoff snapshots are the best fit.
B. Space-optimized instant snapshots are the best fit.
C. File system snapshots are the best fit.
D. Storage checkpoints are the best fit.
