If def is coded as 222120 and qtv is coded as 964, then which of the given options follows the same code?

Given: def is coded as 222120 and qtv is coded as 964

Logic: Code is: (26 - place value of the given letter) 

def is coded as 222120

d=26-4=22, e=26-5=21, f=26-6=20

qtv is coded as 964

q=26-17=9, t=26-20=6, v=26-22=4

Similarly, 

from option A.) abc = 222324

a=26-1=25, b=26-2=24, c=26-3=23(not follows)

from option B.) qpr = 24587

q=26-17=9, p=26-16=10, r=26-18=8(not follows)

from option C.) hik =181715

from option D.) xyz = 2156

x=26-24=2, y=26-25=1, z=26-26=0 (not follows)

Thus, Option C is the correct answer.
