All of the objections listed have been raised against the mind-brain identity theory. 
A) This objection is commonly known as the "explanatory gap" or the "hard problem of consciousness." While neurons firing can be observed and measured scientifically, it is difficult to explain how subjective experiences arise from these physical processes. 
B) This objection is related to the issue of other minds, and whether or not we can know if other beings have mental states similar to ours.
