B Correct answer
Explanation

Option 2 (DCL ARRAY_1 (5,2) DEC FIXED (3)) is NOT correct because PL/I requires the data type attributes to precede the dimension bounds. The correct form is either option 1 (type first, then bounds) or option 3 (bounds with separate type clauses). Option 4 is also invalid syntax.
