There are three kinds of liquids $X, Y,$ and $Z.$ Three jars $J_1, J_2,$ and $J_3$ contain 100 ml of liquids $X,Y,$ and $Z,$ respectively. By an operation we mean three steps in the following order:

• stir the liquid in $J_1$ and transfer 10 ml from $J_1$ into $J_2;$

• stir the liquid in $J_2$ and transfer 10 ml from $J_2$ into $J_3;$

• stir the liquid in $J_3$ and transfer 10 ml from $J_3$ into $J_1.$

After performing the operation four times, let $x,y,$ and $z$ be the amounts of $X,Y,$ and $Z,$ respectively, in $J_1.$ Which of the following is correct?
