The correct answer is:
It is not a very strong fit.
Explanation:
The r-value, or correlation coefficient, tells us how closely our model fits the data.
The r-values range from -1 to 1. -1 is a perfect fit of a decreasing model; 1 is a perfect fit of an increasing model. 0 is no fit at all.
Since our r-value is 0.29, this is much closer to 0 than it is to 1 or -1; this means it is not a very strong fit.
