Which statement is true regarding a cantilever wing?

A cantilever wing is a design characterized by its ability to support itself without the need for external bracing. This design uses internal structural components, such as spars and ribs, to carry the loads produced during flight, allowing the wing to be lighter and providing a cleaner aerodynamic profile.

When a wing is termed "cantilever," it means that all necessary support structures are integrated within the wing's structure itself, eliminating the requirement for external struts or braces seen in other wing designs, such as biplanes. This internal construction enhances the wing's efficiency by reducing drag and improving performance, making cantilever wings suitable for higher-speed aircraft.

The other options suggest that external bracing or additional structural supports are necessary, which contradicts the fundamental characteristic of a cantilever wing. Thus, stating that no external bracing is needed accurately reflects the nature of this wing type and successfully highlights its design advantages.
