Choose the antonym from the given options for the word given below: casuality

Answer: Miracle

Note: The word in the question appears as casuality, which is likely a misspelling of casualty.

• casualty (noun): an accident, someone injured or killed, or loss or harm resulting from an event.

• Why "Miracle" is correct: a miracle is an unexpected, fortunate event or positive outcome, which contrasts with loss, harm, or accident.

• "Usual" and "common" mean ordinary or frequent and are not opposites of harm or loss.

• "Disaster" denotes a harmful or catastrophic event and is similar in meaning to "casualty," so it is not an antonym.
