A Correct answer
Explanation

When UNISYS is not large file enabled, the maximum file size is 262,143 tracks. This limitation exists because of how file size is stored in the system - it uses a specific field size that can represent values up to 262,143 (which is 2^18 - 1, or 18-bit addressing). The other options represent different scenarios: 99,999 is too low, 16,777,152 (2^24) is the large file limit, and 2^20 (1,048,576) is also incorrect for standard mode.
