Select the statements that are true based on the following given information.

D = {x | x is a whole number}

E = {x | x is a perfect square < 36}

F = {x | x is an even number between 20 and 30}

The expression D ∩ E is {1, 4, 9, 16}.
The expression D ∩ F is {12, 14, 16, 18}.
D ∪ (E ∩ F) is {all whole numbers}.
(E ∩ F) is the empty set.
The expression D ∩ (E U F) is 25
