Which of these factors contribute to additional total pressure losses inside the oblique shock diffuser?

Which of these factors contribute to additional total pressure losses inside the oblique shock diffuser? Correct Answer Shock wave interaction with walls

In real life, oblique shock diffusers have viscous flow. The presence of shock waves inside the diffuser leads to interaction with the viscous boundary layer of the diffuser walls which leads to additional pressure losses. There’s also friction involved which makes oblique shock diffusers far from the ideal diffusers which have no total pressure losses.

Statement (I) : When a bluff body moves at supersonic speed in still air, an attached shock wave is produced at its nose causing the flow to be subsonic behind the shock plane. Statement (II) : A normal shock always transforms supersonic flow into subsonic flow causing increase in pressure, temperature and entropy.
