Please help with this question:

D Question 5 1 pts Given a set Q X Q under operations: (x1, y1 ) + (x2, 12) = (x1 + x2, y1 + >2), (x1 , y1 ) . (x2, 12) = (x1X2, y1y2). This is NOT a field, but there are additive identity a and multiplicative identity b. What are they? O a = (1,0) and b = (0, 0) O a = (0,0) and b = (0, 1). O a = (0,0) and b = (1, 0) O a = (0, 1) and b = (1, 1). O a = (0, 0) and b = (1, 1).D Question 6 1 pts Given a set A = {0, 1, z} equipped with addition + and multiplication . defined by the tables: + 0 1 Z 0 1 Z 0 1 Z O 0 0 0 O Z. Z Z. Z Z. Z.
