According to force field analysis, the preferred strategy for unfreezing the status quo is to:

A) remove the driving forces for change.
B) introduce sensitivity training.
C) increase the driving forces and reduce or remove the restraining forces.
D) increase the driving and restraining forces.
E) strengthen existing system and team dynamics.

According to force field analysis, the preferred strategy for unfreezing the status quo is to increase the driving forces and reduce or remove the restraining forces. This helps to shift the balance toward change and create momentum for the desired outcome. Removing the driving forces for change (A) would further reinforce the status quo, while sensitivity training (B) may be helpful in implementing change but is not directly related to unfreezing the status quo. Increasing both driving and restraining forces (D) would maintain the status quo, and strengthening existing system and team dynamics (E) may not necessarily lead to change.
