What Is the Formula for Predicting an Individual's Z Score $\left( r _ { X Y } \right) - \left( z _ { X } \right)$

What is the formula for predicting an individual's z score on the dependent variable from the z score on the independent variable using the correlation coefficient?

A)
$\left( r _ { X Y } \right) - \left( z _ { X } \right)$
B) $\left( z _ { x } \right) \left( z _ { y } \right)$
C) $\left( r _ { X Y } \right) \left( z _ { X } \right)$
D) $\left( r _ { X Y } \right) \left( z _ { y } \right)$
