How many such letter-pairs are there in the word FRONTIER having same no. of letters left between them as they have in the series?

A)2
B)4
C)1
D)3

• We have to find whether for any letter-pair in this word, the same no. of letters exist between them in the alphabet series as that in this word.
  So, consider ON - They are consecutive letters in the alphabet series as well as in this word.
  Also consider NR - There exists 3 letter between them in the alphabets as O, P, Q. In this word also, there exists 3 letter between them (T, I, E).
  
  So ans is 2
