Solution

The correct option is B
diameter

Circumference of a circle is $2 π r$ .

Diameter of a circle, d = 2r,
where r is the radius of the circle.

$\frac{C i r c u m f e r e n c e}{D i a m e t e r} = \frac{2 π r}{2 r} = π$

Therefore, ratio of the circumference of a circle to its diameter is equal to $π$ .
