A Correct answer
Explanation

In IMS DL/I, the segment is the fundamental unit of data retrieval: DL/I can only fetch entire segments, not individual fields within them. Segments contain multiple fields, but those fields are not directly addressable by DL/I calls. This hierarchical structure means access happens at the segment level.
