i. If the first letter is a vowel and last letter is a consonant, both are to be coded as ©
ii. If the first letter is a consonant and last letter is a vowel, both are to be coded as 0
iii. If the first letter as well as the last letter are vowels, both are to be coded as the code of the last letter.
The given sequence is NFRSCA
We are given that If the first letter is a consonant and last letter is a vowel, both are to be coded as 0
In the given sequence N is a consonant and A is a vowel.
Thus, both N and A is to be coded 0. Code word fro F, R, S, C is 5, 3, % and 2 respectively
Thus, the required code word = 053%20
Hence, option D is the correct answer.
