For A  , Difference in appeared and passed candidate = 16 - 12 = 4

For B  , Difference in appeared and passed candidate = 24 - 20 = 4

For C  , Difference in appeared and passed candidate = 14 - 8 = 6

For D  , Difference in appeared and passed candidate = 34 - 26 = 8

For E  , Difference in appeared and passed candidate = 20 - 18 = 2

SO , Difference in appeared and passed candidate is maximum for D.
