Correct. The answer is b. The quality shared by Great Britain, the United States, France, and Germany in the 1850s was that these countries had industrialized, or were in the process of industrializing. Industrial production was, in general, much more efficient than non-industrial production (such as agriculture), which made these four countries more prosperous than their non-industrialized counterparts elsewhere in the world.
