I'm a bit stumped on this one. Polynomial fits? Nah, that's way too complicated for a simple MA(q) process. I'll go with A, it's the only one that makes sense to me.

C'mon, the question clearly says 'time series analysis' - the current value has to depend on the previous values, not some random quotient. Option C is the way to go here.

Option A definitely sounds like the correct description of a MA(q) process. The current deviation depends on the previous q deviations, as the name 'Moving Average' suggests.

I agree, option A is the correct description of a MA(q) process.
