Q2) True or false (1) B = {(a), (b), {c}} is a base of the discrete topology on X = (a, b, c). (X,p.(x,y), (x, z). (y, z)} is not a topology on X (x, y,z). (3) For X = (a, b, c), the excluding point topology is E, {x,q.(a), (c), (a,c), (a, b}}. %3! %3D (2) T= %3D (4) For a discrete topology on X and o AC X. the closure of A is 4.
