Assertion A If regression co efficient of X on Y is greater than one regression co efficient of Y on...........

Assertion (A) : If regression co-efficient of X on Y is greater than one, regression co-efficient of Y on X must be less than one.    (2 marks)

Reason (R) : The geometric mean between two regression coefficients is the co-efficient of correlation. On the basis of the above, choose the appropriate answer :
