Solution:When combining sets A = {a, b} and Set B = {b, d} through the union operation (denoted as A ∪ B), the result is a set that includes all the elements from both sets without repeating any elements. In this case, both sets A and B share the element 'b'. Therefore, the union of these two sets will include 'a' from set A, 'b' shared by both sets, and 'd' from set B, resulting in the set {a, b, d}.
