Which trio lists the three parasite drag types?

Explanation:
Parasite drag is all the drag not directly tied to producing lift, and it has three components: skin friction drag, from the viscous shear on the surface; form drag, from the pressure distribution around the aircraft’s shape; and interference drag, from the interaction of airflow around adjoining parts. Induced drag, on the other hand, arises from lift and wingtip vortices, not from surface friction or shape together, so it isn’t part of parasite drag. Therefore the trio that lists the parasite drag types is skin friction, form drag, and interference drag.
