we know that
<u>The correlation coefficient </u>is a number between
and
that represent the linear dependence of two variables or sets of data
Let

Using the function CORREL in a Excel tool
Find the correlation coefficient for the set of data
see the attached table
the correlation coefficient is 
therefore
<u>the answer is the option B</u>
