The picture is . . . . . . . . the wall. A. on B. under C. in D. None of the above

on
under
in
None of the above

The correct answer is A. on.

A picture can be on a wall in many ways. It can be hung on the wall with nails or screws, or it can be taped to the wall. It can also be a mural, which is a picture that is painted directly on the wall.

The other options are incorrect. A picture cannot be under the wall, because the wall is above the picture. A picture cannot be in the wall, because the wall is solid.

I hope this helps!
