Final answer:
The Sufficiency of Consciousness refers to Principle 5, which views consciousness as a system feature of the brain.
Step-by-step explanation:
The Sufficiency of Consciousness corresponds to Principle 5. Consciousness is defined as awareness and sensitivity concerning a thing that does not include conceptualization. This principle is tied to an understanding that our consciousness is not just a surface feature of the brain, akin to a shape like a parallelogram, but a system feature much like liquidity is a system feature of water. Consciousness, therefore, is a holistic property of the entire system working towards rational decision-making similar to how all molecules in water contribute to its liquidity.
