The correct option is D i j b k
In statements (i), (ii) and (iii), the common alphabet is 'K' and common code letter is 'm'. So, 'K' is coded as 'm'.
In statements (i) and (iii), the common alphabet are 'KE' and common code letter is 'mk' respectively. So, 'E' is coded as 'k'.
Again, in statements (i) and (ii), the common alphabet are 'KC' and common code letter is 'mb' respectively. So, 'C' is coded as 'b'.
Therefore, in statement (i), 'N' is coded as 'i'.
Similarly, in statements (ii) and (iii), the common alphabet are 'KL' and common code letter is 'mn' respectively. So, 'I' is coded as 'j' in it.
Therefore, the word 'NICE' is coded as 'ijbk'.
Hence, option (D) is the correct answer.
