Let S={m.n.k.r.s.t.u.v). Determine if the following collection of the sets is a partition of S. If it is not select ALL requirements of partition that are violated.
[(m.n.k).[r.s.t].(u,v}}
a. This is a partiton
b. This is not a partition because the union of the collection is not equal to S
c. This is not a partition because one of the sets of the collection is empty
d. This is not a partition because the sets in the collections are not mutually disjoint
