which level number cannot be specified in AREA B?
A
Correct answer
Explanation
In COBOL, level numbers 01 and 77 must start in Area A (columns 8-11), while level numbers 02-49 and special level numbers 66 and 88 must start in Area B (columns 12-72). Level 01 is the highest level for group items and is required to be in Area A. Level 55 is valid only in Area B, while 66 (Renames) and 88 (Condition names) are special level numbers that also belong in Area B.
