Answer: C
Acceptance testing is primarily conducted by the users
before sign-off. It is performed from the perspective of the
users to confirm that the system has the required
functionality. Unit testing is used for testing the basic
functionality of a program. Regression testing is used to
compare changes to an application to ensure that the
programs are working the same after a change as before the
change. Integration testing is used to ensure that all of
the programs in an application are working correctly and
that information is flowing correctly.
