The range of simple correlation coefficient is
(a) 0 to infinity
(b) minus one to plus one
(c) minus infinity to infinity
In the case of tangent of an angle, the values increase from 0 to infinity, when the angle increases from 0∘to 90∘.
Has zero any value in integers?
As if we take from 0 to infinity it is positive
And if also take from 1to infinity it is positive
So has zero any value
