Explanation:

Alright, let’s pick this apart:

- Option 1: “it was been extremely informative... and had been widely appreciated.”

This mixes up verb tenses. “Was been” isn’t correct English. You can’t use “was” and “been” together like that. Scratch this one.

- Option 2: “it had been extremely informative... and had widely appreciated.”

The subject is “it,” but “had widely appreciated” is missing a crucial piece—it needs “been.” Without “been,” the sentence falls flat.

- Option 3: “it had been extremely informative... and had been widely appreciated.”

The tense is right. The structure is smooth. Everything matches up. This one nails it.

- Option 4: “it had been extremely informative... and was been to be widely appreciated.”

“Was been to be” is a jumble of verbs that doesn’t work in English.

So, what this really means is:

Option 3 is the only clear, grammatically correct answer. The use of “had been” fits standard reported speech for what the ministry said in the past. All the pieces come together.
