In a certain code language, 'SELFISH' is written as 'TDMEJRI'. How will 'MONITOR' be written in that language?

Given: 'SELFISH' is written as 'TDMEJRI'.

Logic: Add and subtract 1 alternately from the place values of the letters of the given words to get the required codes.

SELFISH $$\rightarrow$$ S + 1 = T; E - 1 = D; L + 1 = M; F - 1 = E; I + 1 = J; S - 1 = R; H + 1 = I

So, 'SELFISH' is written as 'TDMEJRI'.

MONITOR $$\rightarrow$$ M + 1 = N; O - 1 = N; N + 1 = O; I - 1 = H; T + 1 = U; O - 1 = N; R + 1 = S

So, 'MONITOR' is written as 'NNOHUNS'.

Thus, the correct answer is (a).
