I see your point, it makes sense to consider all those factors when evaluating a regression model.

I think including TSS in the evaluation is important, so the answer should be B) (i), (ii), and (iii).

But what about TSS, shouldn't we also consider that in our evaluation?

I think the answer is C), because we need to consider the magnitude of R^2, test for statistical significance, and the sign and magnitude of each regression parameter.

So, should we go with option C then? It includes the magnitude of R2, tests for statistical significance, and the sign and magnitude of each regression parameter.
