Answer 1

Hint: Synonyms are words or phrases that mean exactly or nearly the same as another word or phrase. For example- ‘sad’ and ‘depressed’. Two words that can be interchanged in a context are said to be synonymous relative to that context.
Antonyms are those words that express a meaning opposed to the meaning of another word, in which case the two words are antonyms of each other.

In the given question, the word ‘lethargy’ refers to inactivity; showing an unusual lack of energy.
Let us analyze the options given to us in this question:

Therefore, option (a.) is correct as its meaning is synonymous to that of the given word ‘malaise’.

Therefore, option (b.) is incorrect as its meaning is not synonymous or antonymous to that of the given word ‘malaise’.
