The correct option is C kim
In statement (i), (ii) and (v), the common word is 'na' and the common coded word is 'ja'. So, 'na' is coded as 'ja'.
In statement (iv) and (v), the common word is 'hum' and the common coded word is 'not'. So, 'hum' is coded as 'not'.
Clearly, in statement (v), the word 'jai' is coded as 'kim'.
Hence, option (C) is the correct answer.
