It is a simile because it is a figure of speech involving the comparison of one thing with another thing of a different kind, used to make a description more emphatic or vivid.
In the letter, King, mentions how Socrates made people think by creating tension in the mind, and how he wants to do the same so that in a non violent way, people would become a better version of themselves (not racist) and would therefore come together as a brotherhood. Taking into account these ideas, the correct answer would be option B: "The strain among opposing groups in Birmingham was similar to the creative blockades in ancient Athens, to which Socrates referred". Option A is incorrect because Socrates and King were not seeking the same goal. Option C is incorrect because King never mentions city officials or that Socrates petitioned Greek city-states and finally option D is incorrect because King never mentions that Socrates was trying to achieve harmony between warring groups.
The answer your looking for is A,simple
