A Correct answer
Explanation

The maximum blocksize for a tape file on IBM mainframe systems is 32760 bytes. This limitation exists because the block size field in the data control block (DCB) is 16 bits, and 32760 is the largest value that works reliably with tape formatting requirements. Options B, C, and D are close but incorrect - 32740, 32780, and 32720 are not the standard maximum.
