Question 3.

We can derive our understanding of these two groups from the following: {"...There are, unsurprisingly, several traditions of individualist anarchism, one of them deriving from the ‘conscious egoism’ of the German writer Max Stirner (1806-56), and another from a remarkable series of 19th-century American figures who argued that in protecting our own autonomy and associating with others for common advantages, we are promoting the good of all. These thinkers differed from free-market liberals in their absolute mistrust of American capitalism, and in their emphasis on mutualism..."} 

It is evident that both the groups prioritize individual autonomy; however, the latter does not put emphasis on mutualism. The mistrust of American capitalism is an additional facet marking the difference {but not captured in any of the options}. Option A aptly highlights the difference between the two factions, and is, hence, the correct answer.

Option B: Preferences concerning state configuration or involvement are not discussed in the passage, and hence, we can eliminate this option.

Option C: Perspectives regarding the nature of capitalism are not stated in the passage, and thus, we can effortlessly discard this option

Option D: None of the elements stated in this option can be understood from the passage, and therefore, can be rejected.
