Answer:

Option A. perfect negative association.

Explanation:

We take two points lying on the line representing the best relationship between variables X and Y.

Points are (1, 9) and (2, 8), so the slope will be =
(y-y')/(x-x')=(9-8)/(1-2)=(-1)

Slope of (-1) shows the negative relationship between X and Y which may be represented by Y = (- X), equation of a line.

Therefore, association between variables X and Y can be best described as Option A. perfect negative association
