Answer 1

Hint: Antonyms are those words that express meaning as opposed to the meaning of another word, in which case the two words are antonyms of each other.
In the given question, the word ‘disuse’ refers to ‘to cease the use of; the state of something that has been unused and neglected’.

Complete answer:
Let us analyze the options given to us in this question-
Option (a.), 'prevalent', refers to ‘most frequent or common.’ Therefore, option (a.) is correct as its meaning is antonymous to that of the given word ‘disuse’.
Option (b.), ‘discarded', refers to ‘thrown away.’Therefore, option (b.) is incorrect as its meaning is not antonymous to that of the given word ‘disuse’.
Option (c.), ‘obliterated', refers to ‘reduced to nothingness.’Therefore, option (c.) is incorrect as its meaning is not antonymous to that of the given word ‘disuse’.
Option (d.), ‘unfashionable', refers to ‘not in accord with or not following current fashion; unpopular and considered unappealing or unfashionable at the time.’ Therefore, option (d.) is incorrect as its meaning is not antonymous to that of the given word ‘disuse’.

Note:
 Sometimes the given options in a question where we have to find the opposite of the given word do not exactly mean the opposite of the given word. If this happens, we have to select the option which is the most antonymous to the meaning of the word in the question.
