Given : PROSE is coded as PPOQE
The pattern followed is that the letters at odd position are written as it is, while there is a difference of 2 letters in the alphabets at even position.
Letters at odd position = POE : POE
Letters at even position =Â RS (-2 letters) : PQ
Similarly, for 'LIGHT', letters at odd position i.e., Â LGT will be written as it is and 'IH' will change to 'GF'.
Thus, LIGHT : LGGFT
=> Ans - (D)
