Final answer:

The U.S. Supreme Court has ruled that there are three classes of items that cannot be patented: natural phenomena, abstract ideas or theories, and laws of nature. Correct option is b.

Step-by-step explanation:

The U.S. Supreme Court has ruled that there are three classes of items that cannot be patented:

  1. Natural phenomena, such as gravity or electromagnetic forces.
  2. Abstract ideas or theories.
  3. Laws of nature.

These categories are established to ensure that patents are only granted for novel and non-obvious inventions, rather than things that are inherently part of our world or existing knowledge.
