C. Will have
D. Had been

Answer 1

Hint: Past tense verbs refer to past actions or events. They may be regular verbs that simply end in a "d" or "ed," or irregular verbs that change their spelling to indicate the past tense.
Verbs in the past tense are used to describe an occurrence, case, or circumstance that occurred in the past. There are four types of past tense verbs based on each tense's four aspects that discuss the completion of the event or action.

Complete answer:
The given sentence is in Past perfect continuous tense and keeping in mind to continue the sentence in the same tense to fill up the blank.
Past perfect continuous: - The past perfect continuous is used to speak about activities or events that began before a certain period in the past and were still ongoing at that time:
Ex. It was very difficult to get up for school on Monday. I had been up late the night before working on my essays and was exhausted.

Let us analuze the given options:
Option A) Has been: “Has been” and “Have Been” refer to something that started in the past and has continued into the present, or something that was recently completed. Option A isn't possible because it uses present-tense verb forms. Hence, this option is incorrect.
Option B) Had had: Option B cannot be used since it will result in a grammatical error in the sentence.
Hence, this option is incorrect.
Option C) Will have: Option C is not an option since it uses present-tense verb forms. Hence, this option is incorrect.
Option D) Had been: “Had been” means that something started in the past, lasted for a while, and then finished. It's all in the past now. The second conditional, which is used to express hypothetical or unlikely conditions, is used in this sentence. As a result, the second conditional employs past-tense verb forms. When the word 'I wish' is used in the second conditional to speak about regret that occurred (or did not occur) in the past and is therefore difficult to modify, it is accompanied by past perfect. Hence, this option is correct.
Therefore, Option ‘D’ i.e, Had been the correct answer. So, the sentence will be I wasn’t happy at school. I wish I had been happy.

Note:We may use the past perfect continuous to speak about events that occurred before a specific time in the past and ended, but whose consequences or outcomes were still significant at the time: Ex. It had been raining for quite some time, and the ground was still soaked.
