D is the answer to this question because all the lines are perpendicular and in the 3rd one the bottom lines are perpendicular

## Ans 2:

Class : Class 8
All 4 figure has perpendicular line along perimeter

## Ans 3:

It should be C as it is written that we have to find the perpendicular line for each figure, so there are three figures with perpendicular line but if we consider how many perpendicular lines are there in this picture then it should be 4. This answer is absolutely wrong.
