The Universal Set = { x ∈Z | -4 ≤ x < 4} and A = {0}.What is the complement of A?Group of answer choices{-4, -3, -2, -1, 0, 1, 2, 3}{-3, -2, -1, 1, 2, 3}{-4, -3, -2, -1, 1, 2, 3}{-4, -3, -2, -1, 1, 2, 3, 4}

Consider a general set, A, which is a subset of a general set, Ω. Suppose also that B is the complement of A, i.e. B=Ac=Ω∖A.Next let C be a subset of A (i.e. C⊆A) and D be a subset of B (i.e. D⊆B).Tick the most appropriate answer:D⊆BB∖D=BA∖C=AB∪C=BA∖B=∅A∖C=CA∪D=∅

Let U be a universal set w.r.t. X, Y and Z sets.Then (X ∩ Y′) ∩ Z′ is equal to
