Final answer:
The doctrine that imposes liability without fault for inherently dangerous activities is known as Strict Liability.
Step-by-step explanation:
The legal doctrine that holds individuals engaged in extremely dangerous activities may be held liable even without negligence or malice is known as B) Strict Liability. Strict liability applies to situations where someone undertakes an inherently dangerous activity and is therefore responsible for any damage that results, regardless of the level of care they exercised during those activities. This legal concept is important because it establishes a high level of responsibility on those involved in activities that could pose a significant risk to others or the environment.
