there is some issue with this quesiton.

What is the question
what is the raio of the diameter to the circumfrance of the circle??
for this you don't need any option
ratio = 2r:2*pi(r = 1:pi


Check the question?
What is source.

Im assuming that it is given in the question that Ab=BC=x
bcos otherwise the question is not complete.
Now AC being diameter, angle ABC=90 (Angle in a semicircle is a right angle)
Then AC=diameter=sqrt2*x
Circumference=Pi*x
HEnce ratio=Sqrt2/Pi
