First, we need to find the value of (A $ B). Given that A = 1 and B = -1, and using the operation definition (x$y) = (x - y)/2, we get:

(A $ B) = (1 - (-1))/2 = (1 + 1)/2 = 2/2 = 1

Next, we use this result to find the value of (A $ B) & C. Given that (A $ B) = 1 and C = 2, and using the operation definition (x&y) = (x^2 - y^2), we get:

(A $ B) & C = (1^2 - 2^2) = (1 - 4) = -3

So, the value of (A $ B) & C, when A = 1, B = -1 and C = 2 is -3. Therefore, the correct answer is B. -3.
