a parallelogram is transformed according to the rule (x,y) to (x,y) . which is another way to state the transformation

Answer:
Option d
Step-by-step explanation:
Given is a parallelogram. This is transformed in such a way that it gets back to the original posiiton
This is possible only if rotated about origin with a degree of 360 degrees
If rotated for 90 degrees one quadrant shift only will be there.
180 degrees rotation will shift by two quadrants.
270 degrees rotation will shift by three quadrants.
360 degrees rotation only will shift by four quadrants hence gets back to original posiiton
Hence option d is right
