D
D is closest to being correct.In fact, the patent office will only search existing patents within the realm of the applied product, not all. For example if you apply for a patent on a device to enable a wheelchair to roll more efficiently, the patent office will not search patents for hair dye in its examination, only patents that contain references to wheels, or wheelchairs.
