The set of numbers given in the alternatives by represented by two classes of alphabets as shown in the  given two matrices. The columns and rows of matrix-1 are numbered from 0 to 4 and that of matrix-2 are numbered from 45 to 9. A letter from these matrices can be represented first  by its row and next by its column, for   example `D`can be represented by 12,34 etc and `R` can be represented by 95,97 etc. Similarly, you have to identify the set for the word `PLUS`.
