The Answer is as explained below
The term EFGH1 is wrong. The number at the end of the four letters represents the number of enclosed areas in these four letters. e.g. ABCD as four enclosed areas, 1 in A, 2 in B, 0 in C, and 1 in D. So 4 is appended at the end of ABCD. A similar PQRS has 3 enclosed areas and so on. EFGH does not have an enclosed area. So there should be 0 instead of 1 in this term.
