Solution:
Option(D) is correct

Printing Cost of book = 20% of C.P.

Royalty on book = 15% of C.P.

Difference = (20% of C.P.) - (15% of C.P) = 5% of C.P.

$\text{Percentage difference} = \left(\dfrac{\text{Difference}}{\text{Printing Cost}}\right)× 100\%$

$=\left(\dfrac{\text{5% of C.P.}}{\text{Printing Cost}}\right)× 100\%$

$= 25\%$
