Answer 1

Hint: In a sentence, 'No sooner...than' is used to suggest that one action takes place right after another action.

Complete step-by-step answer:

When 'No sooner...than' is used at the beginning of the sentences, then the auxiliary verb always goes before the subject.
An auxiliary verb is used in forming the tenses, moods, and voices of other verbs in a sentence. ‘No sooner’ always states the event that occurred first among the rest.

The given sentence which uses ‘As soon as’ can be transformed using ‘No sooner...than’ by beginning this sentence with 'no sooner' followed by the first event, and then 'than', followed by the second event.
Amongst the given options, option (d.) is the correct answer as the auxiliary verb 'did' is before the subject, which is 'Matthew'. 'Did' should be used as the sentence given is in the past tense.

Thus, options (a.), (b.) and (c.) are grammatically incorrect

Note: ‘No sooner’ is the negative form of ‘As soon as’. It is usually always accompanied by an auxiliary verb in the past tense.
