In a certain code language, 'so it be' is written as 'lor kor nor', 'it is done' is written as 'zor kor tor', and 'be yourself' is written as 'nor xor'. How will 'so' be written in that language?

lor

Give; In a certain code language, 'so it be' is written as 'lor kor nor', 'it is done' is written as 'zor kor tor', and 'be yourself' is written as 'nor xor'.

So,

So  it  be  =  lor  kor  nor

it  is  done  =  zor  kor  tor

be  yourself  =  nor  xor

Thus,

it is coded as kor, be is nor and so is lor

Therefore, lor is correct.
