Question: If TAP is coded as SZO then howIs FREEZE coded?
Each letter in the word TAPis moved one step backward to obtain the corresponding Hence to obtain the code for FREEZE we will have to move each alphabet one alphabet behind. Hence we will have to code F as E, R as a,E as D and z as Y. Hence, correct option is (4).
