In the following sentence, a part of the sentence is underlined. Below are given alternatives to the underlined part, which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose the option ‘No improvement’. No sooner had they completed the work, than they demanded the wages.?

Option 4 : No improvement

The structure 'no sooner' is used to describe something that happens immediately after something else.

For example,

No sooner had I stepped out, than it started raining.

This sentence can be rewritten using 'as soon as' but it would require the structure of the sentence to be changed.

'As soon as they completed the work, they demanded the wages'.

When no sooner comes at the beginning of a sentence, we use inverted word order. That means the auxiliary verb comes before the subject.

Therefore, the correct answer is option 4.
