Identify the adjunct in the given sentence:
She is usually on time.
A. She
B. Usually
C. Time
D. None of the above

Hint: We have to find the adjunct for the sentence given in the question “She is usually on time”. The meaning of adjunct is it is a word or a phrase which is not necessary or compulsory to the structure of the clause but also adds some extra meaning to it.

Complete answer:
Option A is She is an incorrect answer for the above-asked question as she is the subject in the sentence and we cannot form a sentence without the subject and if we make one it would not have any meaning. Option B is Usually, it is the correct answer for the above-asked question, because usually is an adverbial adjunct and we can also write the sentence without this word as it is not necessary to add this word.
Option C is Time, it is not an appropriate choice for the question asked above as ‘time’ is a complement and it is necessary to add a complement to make a sentence meaningful.
Option D is None of the above, it is also not a correct choice for the question as the answer of the question asked is option B that is ‘usually’ so we cannot say that all the options given do not have the right answer or none of the above is correct.

Hence, the correct option is B

Note:
A word or phrase that constitutes an optional element or is considered of secondary importance in a sentence is called an adjunct.
