A Correct answer
Explanation

Parabolic dunes form when vegetation partially covers a sand surface, anchoring some areas while allowing sand to move around them, creating a distinctive U-shaped form. Barchans are crescent-shaped dunes without vegetation, seifs are longitudinal dunes, and a strait is a narrow water body between land masses.
