Accepted Answer

The correct order from the outermost to the innermost layer is epicuticle, exocuticle, and then endocuticle. The epicuticle is the outermost layer that provides waterproofing, the exocuticle is the middle layer that provides additional strength, and the endocuticle is the innermost layer that provides structural support.
