Answer:
The answer to your problem is, A
Step-by-step explanation:
Lets list our options
A. An object is standing still at a position of 6 meters from the student.
B. An object is moving at a variable speed away from the student.
C. An object is standing still immediately next to the student.
D. An object is moving at a constant speed of 6 m/s away from the student.
A = Correct our student can see the object
B. = Not correct if he is just standing and not moving and just looking that means he can no see a moving object he would to have to move
C. = Maybe it could be correct it is right next to our student but they don’t give us any description where he is looking so it could be correct
D. = Not correct like I said in the b answer: if he is just standing and not moving and just looking that means he can no see a moving object he would to have to move.
Which leads to our most valuable option which is. A
Thus the answer to your problem is, A
