The correct answer is A. (1, 1)

The midpoint of a line segment joining two points (x1, y1) and (x2, y2) is given by the formula ((x1 + x2)/2, (y1 + y2)/2).

In this case, we have P(-3, 5) and Q(5, -3), so the midpoint is ((-3 + 5)/2, (5 + (-3))/2) = (1, 1).

So, the midpoint of the line joining P(-3, 5) and Q(5, -3) is (1, 1).
