Step 1: Identify the figure of speech used.
The sentence directly compares the bureaucratic system to a labyrinth of red tape without using words like “as” or “like”.
Step 2: Understand the meaning of the comparison.
A labyrinth suggests something complex, confusing, and difficult to navigate.
Here, the bureaucratic system is described as similarly complex and obstructive.
Step 3: Analyze the options.
(1) Simile – incorrect because similes use “like” or “as”.
(2) Metaphor – correct because there is a direct comparison without comparative words.
(3) Paradox – incorrect because there is no self-contradictory idea.
(4) Euphemism – incorrect because no mild or indirect expression is used.
Step 4: Conclusion.
The figure of speech used in the sentence is a metaphor.
