In the above given arrangement, there are two positions left out of which A4 may occupy any one of the positions.

1) A4 is at fifth position from top → False (It is not definite)

2) Number of articles above A4 are four → False (It is not definite)

3) A4 is just between A6 and A8 → False (It is not definite)

4) A4 may be just above A1 → True (It is possible)

Hence, ‘option 4’ is the correct answer.
