The sudden job loss turned out to be a blessing in disguise for him.What does the underlined idiom mean?

Explanation

The idiom 'blessing in disguise' refers to a situation that initially appears to be negative but ultimately results in something good. In the context of the sentence, the job loss seemed unfortunate, but it led to unexpected advantages for him, such as new opportunities or personal growth. The other options are incorrect because they do not convey the positive transformation implied by the idiom. 'A terrible tragedy' focuses solely on the negative, 'an unexpected enemy' suggests conflict, and 'a false promise' implies deceit, none of which represent the nuanced meaning of finding good in a bad situation.
