Solution

The correct option is A

The value of y increases


Explanation for the correct option.

Given that, the correlation coefficient is positive & the value of x increases.

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

So, if the value of x increases then the value of y increases.

Hence, option A is correct.
