The main objective of force field analysis is to help change agents to:

A) identify ways to force employees to change their behavior.
B) find ways to increase the driving forces for change.
C) diagnose the situation better by understanding the driving and constraining forces for change.
D) determine whether change is necessary at all.
E) Do 'A' and 'B' only.

The main objective of force field analysis is to diagnose the situation better by understanding the driving and constraining forces for change. It aims to identify the forces that support and hinder change so that change agents can develop strategies to mitigate the barriers and enhance the drivers of change. It does not aim to force employees to change or determine whether change is necessary at all. Option E is incorrect as it only includes part of the correct answer.
