Answer:
Let's r and R are the radius of Small and large circle respectively.
Hence r = 4 R , because r = R/4
Given
Diagonal AC=BD=46cm
Now from the figure,
r+r+R+R+r+r<46 cm
Or, r+r+4r+4r+r+r<46cm
Or, 12r<46cm
Now, checking for each option
a. When r= (5-√2)
Then, 12×(5-√2)<46cm
Or, 43.029<46cm
Hence, option (a) is correct.
