The following regression model studies the effect of father's height on child height, where C_height records the child's height in cm, F_height_in records the father's height in inches, F_height_cm records the fat height in centimeters (1 inch=2.54 cm), and Fam_inc records the family's annual income in AUD. C_height = Bo + BF_height_in + B2F_height_cm + B3 Fam_inc + U Which of the following is true? Select one: O a. the model suffers from multicollinearity O b. the model suffers from perfect collinearity O c. B = 2.54 B
