• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Look at the front: base slab, a tall back wall with a window on its right part, and a slanted rib in the middle whose edges end on the slab line.

Answer 1

The Correct Option is C

The arrow looks at the front of the object, so we draw the front elevation.
The object is a base slab with a tall back wall rising to the full height. A slanted rib runs up from the front of the slab, in the middle (about a third of the width, starting about one quarter from the left). The back wall to the right of the rib has a square window in it.
In the elevation, the slab is a strip along the bottom. Above it the wall is divided into three vertical parts by the rib: a plain left part, the rib in the middle and the right part with the square window. The two vertical lines of the rib run from the top down to the slab line, and the rib joins the slab front face without any line between them, because the front face continues into the rib.
Option (1) draws a line across the middle, option (2) takes the rib down through the slab, and option (4) puts the window in the left part. Only option (3) has the window on the right, the rib lines ending on the slab line and no line across the foot of the rib.
