Which of the following best defines 'bedlam'?

The term 'bedlam' originates from the name of the Bethlem Royal Hospital, a former psychiatric institution in London known for its chaotic and disorganized environment. Over time, 'bedlam' has evolved in usage to refer broadly to any scene or state characterized by extreme confusion, uproar, or disorder. The definition captures the essence of tumult and chaotic situations where normal order is completely disrupted.

The other options all imply calmness, organization, or peacefulness, which starkly contrast with the meaning of 'bedlam.' Thus, the choice that reflects a state of extreme confusion and disorder accurately mirrors the historical and contextual significance of the word.
