Which option is an example of 'Chemical Force CDU'?

The example of 'Chemical Force CDU' is most accurately represented by employing pepper spray as a deflection method. This is because 'Chemical Force' encompasses techniques that utilize chemical agents to manage situations, particularly in crowd control scenarios where less lethal options are preferred.

Pepper spray is a common non-lethal chemical agent used by law enforcement to incapacitate individuals temporarily by causing irritation to the eyes, skin, and respiratory system. This approach is intended to defuse potentially violent situations without resorting to more severe measures, making it consistent with the principles of Chemical Force in the context of crowd management.

The other options involve either physical means of control or defensive tactics rather than the use of chemical agents, thus distinguishing them from 'Chemical Force'.
