What does the term "Catch-22" represent, as coined by Joseph Heller?

The term "Catch-22," as coined by Joseph Heller in his novel of the same name, embodies the concept of an absurd situation where an individual is trapped by contradictory rules or regulations, leading to no viable options to escape or resolve the dilemma. In the context of Heller's work, the protagonist, Yossarian, faces the paradox of needing to be declared insane in order to avoid dangerous missions, but the very act of seeking to avoid those missions through a request is taken as an indication of sanity. This illustrates the illogical nature of bureaucratic rules that create a no-win scenario, which has since entered the broader cultural lexicon to describe similar predicaments in various contexts.

The other options, while they represent potential elements related to military or societal structures, do not encapsulate the core essence of what "Catch-22" signifies in the context of Heller's narrative and its commentary on the absurdities of war and institutional logic. The term serves as a critique of the flawed systems that govern individual actions and decisions, making the second choice the correct understanding of its meaning.
