Fawzi's Situation (Scenario) Fawzi Was Not Handling the Change in His Department Well

Fawzi's Situation (Scenario)
Fawzi was not handling the change in his department well. The company had recently changed hands, and even though no jobs had been lost, people had been changing jobs and were being asked to move to different locations. The new leadership had a completely different outlook than the management he had worked under for the past 21 years. Fawzi found that he was unable to concentrate at work and generally felt like he did not like his job anymore. At home he was getting headaches and having trouble sleeping, which only enhanced his feeling that things were not going to work out well for him. When he thought about it, he had always hated change. He had chosen this line of work partially because it was considered stable (boring to some) and predictable. Fawzi's new boss kept trying to convince him that he was a valuable employee and that new opportunities, along with salary increases, were in store in his future. Unfortunately, Fawzi felt like he never knew what to expect from day to day and what he really wanted was to have things return to the way they were.
-Fawzi is obviously resistant to the change being introduced in his organization. Which of the following reasons is most likely the primary driver of Fawzi's resistance?

A) concern over personal loss
B) belief that change is not in the organization's best interest
C) habit
D) uncertainty
