Answer 2

Dear Friend!!!  : )
I would say all three are good and attractive to write in exam.
As per me, for quick learning and less efforts, I would learn the third one since it is the shortest.
To make a good impression in front of the examiner, I would suggest you the first one since it is the longest.
Rest is all up to you, what ever you choose, I guess it would be correct.
Bye!! 
Have A Nice Day ^_^
