The question states that: If A is a subset of the universal set U, the __________ of A is the set of elements of U that are not elements of A. This set is demoted by A '. Using set builder notation, A ' = {x : x € U but x E/ A}
The above statement is the definition of the complement of the set.
The notation A' is used for the complementary set for the set A.
Hence the option complement is correct.
The first option which states complement is correct.
