Final answer:
The best risk reduction technique is described in Option B, where a company chooses to train users on more secure methods of operation to reduce risks associated with security breaches.
Step-by-step explanation:
The scenario that BEST describes a risk reduction technique is: B. A security control objective cannot be met through a technical change, so the company implements a policy to train users on a more secure method of operation. This scenario illustrates how a company can actively reduce risk by changing behavior and procedures to enhance security. It aligns with practices like insurance companies offering lower rates for businesses that install top-level security and fire sprinkler systems. Training users in more secure methods is a proactive step towards reducing the likelihood of security breaches and can be considered an effective way of managing risk.
