If in a certain code language $SISTER$ is coded as $535301$,$UNCLE$ as $84670$ and $BOY$ as $129$,how will $SON$ be coded in that code language?

In a certain code language:
$(A)$ 'pit na som' means 'bring me water'
$(B)$ 'na jo tod' means 'water is life'
$(C)$ 'tub od pit' means 'give me toy'
$(D)$ 'jo lin hot' means 'life and death'
To find out the answer to the above question (which is implied to be decoding the language),which of the following statements can be dispensed with?

If in a certain language,$MACHINE$ is coded as $LBBIHOD$,which word would be coded as $SLTMFNB$?

The word $EXPAND$ is encoded using four different rules,resulting in four different codes. Identify the rule applied to the word $TRAVELLER$ to obtain the code $USBWFMMFS$.

If in a certain language,$ENTRY$ is coded as $12345$ and $STEADY$ is coded as $931785$,then state which is the correct code for "$NEATNESS$".

Which of the following words would correctly decode the word $ZHOFRPH$ if the simple alphabet shifting code is used?
