In a certain code language, 'PRINT is coded as '38724' and 'NITRO' is coded as '23687". What is the code for 'O' in the given code language?

Correct option is C

Comparing 'PRINT' = '38724' and 'NITRO' = '23687', and aligning letters with their codes, 'O' is the only letter in 'NITRO' not in 'PRINT', corresponding to the remaining code '6'.
