To describe a record the level numbers may be chosen from

  1. 01 to 77

  2. 01 to 49 and 77

  3. all odd numbers from 01 to 49

  4. 01 to 49

D Correct answer
Explanation

Level numbers in a record are limited to the range 01‑49; this range covers all defined levels while keeping the numbering scheme simple. Options offering 01‑77 or adding 77 extend beyond the defined set, and using only odd numbers would skip valid even levels, making them incorrect.

AI explanation

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.
