Let A = (a, b, c, d, e) and the equivalence relation on the set A is defined as follows: R = {(a, a),(a, e), (b, b), (b, c), (c, b), (c, c), (d, d), (e, a), (e, e)}. Which of the following form a partition of the set A? a) ([a, e], [b, c), {d}} (a,b,c,d,e) b) c) ([a, c, e], [b, d}} d) (a, b, c, d], [e}}
