I feel like I saw something about the X's needing to be independent in a practice test, but I might be mixing it up with correlation.

I practiced a question about residuals needing to be normally distributed, but I can't recall if that's a strict requirement for MLR validity.

I think option C sounds off because MLR can be used in observational studies too, not just experiments.

I remember that MLR assumes the inputs should be independent, but I'm not sure if that's the same as saying they're not correlated.

Wait, I'm not sure about this. Aren't the inputs supposed to be uncorrelated? I'm going to have to review my notes on the MLR assumptions again before answering this.

Okay, I've got it. The key is that MLR doesn't require a deliberate form of experimentation, unlike some other regression techniques. I'm confident that's the right answer.
