How do you define a table/Array in COBOL using Index?

  1. 01 ARRAYS. 05 ARRAY2 PIC X(6) OCCURS 20 TIMES INDEXED BY WS-INDEX

  2. 01 ARRAY2 PIC X(6) OCCURS 20 TIMES INDEXED BY WS-INDEX

  3. 01 ARRAYS. 05 ARRAY1 PIC X(9) OCCURS INDEXE BY 10 TIMES

  4. 01 ARRAYS. 88 ARRAY2 PIC X(6) OCCURS 20 TIMES INDEXED BY WS-INDEX

B Correct answer
Explanation

Option B shows correct COBOL array syntax: the data name at level 01 with PIC clause, OCCURS clause specifying the count, and INDEXED BY clause for the index variable. Option A unnecessarily nests under a group, Option C has 'INDEXE' typo, and Option D incorrectly uses level 88 (reserved for condition names).
