Chemoautotrophs are a broad nutritional category of prokaryotes that use chemical energy to synthesize organic compounds from inorganic materials. This process is known as chemosynthesis, and it is an important energy source for many ecosystems, particularly those in deep-sea habitats where sunlight is scarce. The other choices (A, B, C, E) are more specific nutritional categories of prokaryotes, and not as broad as chemoautotrophs.
