From the sets given below, select equal sets :
A = {2, 4, 8, 12}, B = {1, 2, 3, 4},
C = {4, 8, 12, 14}, D = {3, 1, 4, 2},
E = {-1, 1}, F = {0, a}
G = {1, -1}, H = {0, 1}
From the given sets, we see that sets B and D have same elements and also sets E and G have same elements.
∴ B = D = {1, 2, 3, 4} and E = G = {-1, 1}.
