  4. Nav.Direction d = Nav.Direction.NORTH;

D Correct answer
Explanation

The Direction enum is nested inside the Nav class, so it must be accessed as Nav.Direction. To use the enum constant NORTH, the full qualified name Nav.Direction.NORTH is required. Options A, B, and C miss either the outer class reference or the enum type.
