To describe a record in programming, level numbers are used. The level numbers indicate the hierarchy or structure of the data in a record. Each level number represents a specific level of the record's structure.
In COBOL programming, the level numbers typically range from 01 to 49.
Option A) 01 to 77 - This option is incorrect because the level numbers in COBOL do not go up to 77. The highest level number is 49.
Option B) 01 to 49 and 77 - This option is incorrect because the level number 77 is not part of the range of valid level numbers in COBOL.
Option C) all odd numbers from 01 to 49 - This option is incorrect because the level numbers in COBOL are not restricted to odd numbers only.
Option D) 01 to 49 - This option is correct because the valid level numbers in COBOL programming range from 01 to 49.
Therefore, the correct answer is Option D) 01 to 49.
