D sounds like it's trying to trick me. The Correlation Coefficient and r^2 are related, but not in that way!

I'm torn between A and C. The r^2 value is the square of the Correlation Coefficient, so it would be larger than the absolute value of r.

I think option C is the correct answer. The Coefficient of Determination is always less than or equal to the square of the Correlation Coefficient.

Hmm, I see your point. But I still think A) makes more sense because r2 value is always smaller than r.
