• A. 's just arrived / has just arrived
• B. 'd just arrived / had just arrived
  
• C. is arrived
  
• D. 've just arrived / have just arrived

Answer 1

The correct option is D 've just arrived / have just arrived

The present perfect tense is used to describe something that happened in the past, but the exact time it happened is not important. It has a relationship with the present.

Have/has + past participle makes the present perfect

In this sentence we would be using present perfect tense as the conditions match. Now since, the whole sentence is in the second person, we would be using "have" and not "has".

("have" is used in case of first and second person framed sentences.)

Now, for the past participle, it the form of a verb, typically ending in -ed in English, which is used in forming perfect and passive tenses and sometimes as an adjective. In this case the past becomes, "arrived"

Option D is correct
