• A. Had the vehicle been parked in the wrong place, it would have been towed away.
• B. Whether the vehicle was parked in the wrong place, it would have been towed away.
• C. Unless the vehicle was parked in the wrong place, it would have been towed away.
• D. Has the vehicle been parked in the wrong place, it would have been towed away.

Answer 1

The correct option is A Had the vehicle been parked in the wrong place, it would have been towed away.

'If' is a conjunction which is used to express uncertainty about whether an action (or event or condition) will occur. In the event, the particular action (or event or condition) occurs, then the other event is likely to occur.

Option A: The auxiliary verb, 'had' can be used to replace the word' if' in a conditional sentence in the past tense. The given sentence is in the past tense. Hence, 'had' can be used. 'Had' is used along with the past participle form of the main verb. The main verb is 'was parked' whose past participle form is 'been parked'. So, the clause, 'If the vehicle was parked in the wrong place' can be replaced by 'Had the vehicle been parked in the wrong place'. Hence, option A is correct.

Option B: Whether' is a conjunction which is used to express a choice between two alternatives or events. Here, there is no such reference. Hence, this option is incorrect.

Option C: 'The word, 'unless' is used to replace 'If... not'. In the given sentence, the word, 'not' isn't used. Hence, this option is incorrect.

Option D is incorrect as a conditional sentence cannot start with the words, 'Has I'. Further, this is also grammatically incorrect as the auxiliary, 'has' is used with third person singular nouns/pronouns and not with I (first person singular pronoun).
