Correlation can have a value:  

• 1 is a perfect positive correlation .

• 0 is no correlation (the values don't seem linked at all)

• −1 is a perfect negative correlation

Since , its coefficient lies from -1 to 1.( B  is true )

If  r = 1 then it has strong relationship between two variable  ( C is true)

If r= 0 the it has no relation ( D is false )

If r = -0.9 the it has high negative correlation ( E is true )
