A Correct answer
Explanation

A Partitioned Dataset (PDS) requires a directory to track member names and locations, so Directory Block must be non-zero. A Physical Sequential (PS) dataset has no directory structure, so Directory Block is zero or omitted. The block size field alone doesn't distinguish between PS and PDS - it's the presence/absence of a directory that differentiates them.
