The correct answer is C
If you use mapping variables in a session, you can clear any of the variable values saved in the repository by editing the session. When you clear the variable values, the Integration Service uses the values in the parameter file the next time you run a session. If the session does not use a parameter file, the Integration Service uses the values assigned in the pre-session variable assignment. If there are no assigned values, the Integration Service uses the initial values defined in the mapping.
