A word is represented by only one set of numbers as given  in any one of the alternatives. The sets of numbers given  in the alternatives are represented by two classes of  alphabets as shown in the given two matrices. The  columns and rows of Matrix-I are numbered from 0 to 4 
and that of Matrix-II are numbered from 5 to 9. A letter  from these matrices can be represented first by its row  and next by its column, for example 'K' can be represented  by 13, 34 etc and 'Z' can be represented by 85, 79 etc.  Similarly, you have to identify the set for the word 'PLOT'.
