Answer:
Option C is correct.
The value of r=0.2 represents the weakest correlation.
Step-by-step explanation:
Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.
Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.
From the options, the only r-value that is very close to 0 is 0.2.
Therefore, the r-value represents the weakest correlation is, 0.2

I assume that if we write the equation in its mathematical form it will appear like this:
T = 50 + (N - 40)/4
Substituting the value of T given,
58 = 50 + (N-40)/4
The value of N from the generated equation above is equal to 72. Therefore, the Snowy Tree Crickets chirp 72 times per minute at a temperature of 58°F.
