I am so confused between MSS and PSA and SA does anyone know a simple way to explain this?

I am still lost on answer choice C, I got the question right in the blind review, but I am still lost about the logic behind C and what makes it wrong, any advice?

I understand it when I watch the video, but when I attempt to do it by myself I always get stuck when trying to chain concepts together. Does anyone maybe have a trick they use? Especially if the statement has a lot of negate statements, I get lost when doing it on my own.
