A rooky problem

Probability Level 2

On a $2017$ by $2017$ chess board there are $2017$ rooks so that no rook attacks another. Then each rook makes a move like a knight. After that will there always be two rooks attacking each other?

No- it depends on the knight moves that were made by the rooks No- it depends on the knight moves made and the starting configuration. No- it depends on the starting configuration Yes
