Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. you had completed.
This sentence is an example of a third conditional structure, which is used to talk about hypothetical situations in the past that did not happen.
The third conditional structure: If + past perfect (had + past participle), subject + would have + past participle.
In this sentence, 'had you been working regularly' serves as the conditional clause in inverted form.
The main clause should follow the "would have + past participle" structure to indicate the hypothetical result.
