Step-by-step explanation:
C. is the closest to being correct. It predicts lengths from 28 to 34, and this agrees with the observations.
A. is wrong. The equation has a negative slope, but the leg lengths increase with waist size (positive slope)
B. is wrong. Leg length increases with waist size.
D. is wrong. If it were correct, leg lengths would range from 46 to 58, and these predicted values are much greater than those observed.
