Option B correctly lists all subsets of the set K = {6, 7, 8, 9}, including the empty set ($\varnothing$), all single-element subsets, all two-element subsets, all three-element subsets, and the set itself as a four-element subset, without repeating subsets or listing them in different orders (since order does not matter in sets).
