The correct option is A Germany
At its birth Germany occupied an area of 208,825 square miles (540,854 square km) and had a population of more than 41 million, which was to grow to 67 million by 1914. The religious makeup was 63 percent Protestant, 36 percent Roman Catholic, and 1 percent Jewish. The nation was ethnically homogeneous apart from a modest-sized Polish minority and smaller Danish, French, and Sorbian populations. None of the other countries have a high majority of one single ethnicity and are hence, incorrect.
