B Correct answer
Explanation

For a single alphanumeric character 'M' in a variable field (#VAR), Fixed Format storage is preferable. Fixed storage is predictable and efficient for short values. Default Compression and Normal Suppression are variable-length techniques that add overhead for single characters. Fixed format avoids the length byte overhead.
