In the given figure both the end sides are flat. So, this rules out option D which has a dent on right side.

Now, if we draw a horizontal line from the end positions of the given figure (both end positions are at same level), we can see $2$ rectangle projections and $3$ dents out of which $2$ are $L$ shaped but not with same orientation. So, the correct option should complement this.

• Option A: satisfies the required criteria of having $3$ projections out of which $2$ are $L$ shaped having different orientation and $2$ rectangle dents.
• Option B: has only one dent.
• Option C: the orientation of the $2$ $L$ shapes are the same ans so cannot fit the given figure.

Correct Option: A.
