Explanation:

- In the sentence "I don’t think we can talk to him at all. He wasn’t listening," the tense is past continuous, suggesting an ongoing action in the past.

- Option 1: "didn’t listen" - Implies a past action, but lacks the continuous aspect. It's grammatically correct, but shifts the aspect from continuous to simple past.

- Option 2: "doesn't listen" - Implies present habitual action. Suggests he generally doesn’t listen, changing the sentence meaning.

- Option 3: "hadn’t listened" - Refers to a past perfect action before another past action. Not suitable without a specific past reference point.

- Option 4: "will not listening" - Incorrect grammar. Should be "will not listen" for future tense.

The most suitable option depends on context, but if the intended meaning is an ongoing or habitual present action, then Option 2: "doesn't listen" is appropriate.
