Answer:
The correct answer is letter "B": Eliminitivism.
Explanation:
Eliminative materialism also known as eliminativism is the revolutionary argument that our common-sense perception of the brain is profoundly wrong and that some or all of the common-sense mental states do not exist and have no influence in well-established cognitive science.
In the case given, we are eliminating the basic perception of having a headache for "My C-fibers are firing" which is much more of a scientific description of the simple pain in the head.
