The correct answer is A. The best Masters are the ones who act as fathers towards their subjects.
The relationship between Robinson Crusoe and Friday is akin to that between a father and a child, since Crusoe seeks to transform Friday from a cannibal into a civilized man. The novel reveals the typical attitude of Europeans toward other peoples: they are viewed as backwards and uncivilized, and the "solution" is to make them more European. During the 18th century, this civilizing process was often compared to the education of a child; Immanuel Kant, for example, referred to the Enlightenment as the "coming of age" of mankind. In the novel, Crusoe's attitude towards Friday is kind but stern, since he seeks to eradicate Friday's native customs and convert him to Christianity. Crusoe ultimately succeeds, and Friday is assimilated into European culture.
