Risk acceptance is the mitigation option that has no direct cost because the organization chooses to acknowledge the risk without taking additional action to reduce, transfer, or eliminate it. In Human Resource and organizational management, this approach is typically used when the cost of mitigation exceeds the potential impact of the risk or when the risk level is considered minimal. While there may still be indirect consequences if the risk materializes, no immediate financial investment is required to manage it. In contrast, risk avoidance may involve changing operations, risk limitation requires implementing controls and safeguards, and risk transference often includes costs such as insurance or outsourcing. Therefore, option B is correct because risk acceptance does not require upfront expenditure, making it the only option with no direct cost.

A suicide attack is a tactic where the attacker intentionally sacrifices their life to ensure the success of the mission. This is seen in tactics such as suicide bombings or vehicle-borne IEDs. It is used to maximize impact, instill fear, and often guarantees media attention.
