Which sentence indicates that the video has already been seen?

• A. He hasn't seen it.
• B. He's already seen it.
• C. He will see it.
• D. He hasn't seen it yet.

Answer: (B)

This question tests recognizing time expressions that show a completed action up to the present moment. The sentence with “He’s already seen it” uses the present perfect tense in a way that means the video has been watched at some point before now, and the adverb “already” emphasizes that it happened earlier than expected or earlier than today. So it clearly indicates the video has been seen.

The other options don’t convey that completion. “He hasn’t seen it” says the video has not been seen up to now. “He will see it” points to a future action. “He hasn’t seen it yet” also means it hasn’t happened up to now but might happen later.
