answer will be (A)...and why you will get 4 eigen vectors, only 2 eigen vectors corresponding to 2 eigen values....if you are saying in this sense """""one time take x as arbitary next time take y as arbitary""""".....it will not make 4 eigen vector, it is still two eigen vectors, because ultimately you will take out common arbitary...

i dont know if you understand what i am saying..
