Answer 2

Answer:

If only he had informed us before hand, none of this confusion would have happened.

Explanation:

• Any continuous tenses cannot be used  as it denotes an action that started in the past, continued in the past, and also ended in the past. The first part of the sentence indicate that the action is not being done, and hence it is leading to a present conflict.
• We cannot use 'has been' as it is a present perfect continuous tense
• Same as 'had been' as it is a past perfect continuous tense.
• 'Hadn't had' implies if one hadn't done what they did, which is exactly the opposite to what the sentence is initiating.
• 'Had' is a Past Perfect Tense and is followed by a past particle 'informed', hence 'had' is the answer.
