Answer

Brief Explanations:

Hovercraft and hydrofoils reduce water - air interface resistance by gliding above water, enabling a fast, smooth ride. Option A is incorrect as they don't maintain wave contact. Option C is wrong as not all use airplane engines. Option D is not the main reason for the fast, smooth ride.

Answer:

B. They reduce drag by gliding above the water.
