In the following figure, square represents Philosophers, triangle represents Police Officer, circle represents Pharmacists and rectangle represents Americans. Which set of letters represents Pharmacists who are not police officers ?

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 'C' can be represented by 43, 14 etc and 'Q' can be represented by 89, 65 etc, Similarly, you have to identify the set for the word 'YANK'.
