First, we need to find the value of (A ? B). Given that A = -1, B = 2 and the operation ? is defined as (x + y)/2, we substitute A and B into the operation:

(A ? B) = (-1 + 2)/2 = 0.5

Next, we need to find the value of (A ? B) $ C. Given that (A ? B) = 0.5 and C = 1 and the operation $ is defined as (x - y)/2, we substitute (A ? B) and C into the operation:

(A ? B) $ C = (0.5 - 1)/2 = -0.25

So, the value of (A ? B) $ C, when A = -1, B = 2 and C = 1 is -0.25. Therefore, the correct answer is D. -0.25.
