1. (1 point) For r, y E R, consider the statement: If ry = 0 then r = 0 or y = 0. (t) To prove (t) by contradiction, what do we assume? No explanation needed. (A) Assume we have r, y E R with ry = 0, z = 0, and y = 0. (B) Assume we have r, y e R with ry = 0, r / 0 and y / 0. (C) Assume we have r, y ER with ry / 0, r = 0, and y = 0. (D) Assume we have r, y e R with ry / 0, 1 4 0 and y * 0. Answer (write the correct letter)
