Let we have the following set of frequent 2-itemsets L2 = {{a,b}, {a, c},{a, e}, {b, c}, {b, d}, {b,e}}. Choose C3, the correct set of candidate 3-itemset generated and pruned by the Apriori algorithm. Select one: O (a,c,d,e) O {{a,b,c,d), {a,c.d,e), (a,b.c,e), (a,b,d,e}} O {{a,b.c.d), {a,c,d,e), (a,b,c,e}} O {{a,b,c,d), (a,c,d,e), {a,b,d,e)} O {{a,b,c,d},(a,c,d,e}} O (a,b,c,d) v
